Specify the color codes in a batch file by ECHOing the foreground and/or background color codes (from the following table) followed by the text to be formatted, followed by the ANSI default (Esc[0m) to reset the terminal back to the default colors.These codes are the same as those used in a Unix/Linux/VT 100 terminal though the colors may be slightly different shades.

Color schemes in SecureCRT are local configuration settings that instruct SecureCRT which foreground and background colors to use for text displayed in the terminal. These color scheme configurations include a collection of independent foreground and background colors SecureCRT will use for displaying normal, bold, underline, and blink attributes.
A remote host (or an application running on the remote host) may send ANSI color escape sequences to specify the foreground and background colors a terminal should use for displaying subsequent text received. Typically ANSI color is comprised of an escape sequence that includes a representation for one or more of 16 unique colors. Eight of the escape sequences correspond to what are called normal colors and the other eight typically correspond to bold (or bright) versions of those colors.
Depending on the color codes sent by the remote application when ANSI color is in enabled, the default colors may not be ideal for visibility in some situations. ANSI colors for Normal and Bold attributes can be modified globally in SecureCRT's Global Options.
I just got a Mac after working with Ubuntu Linux for some time. Among the many things I'm trying to figure out is the absence of colors in my terminal window- like the ones that are shown (on Linux) when running ls -la or git status.
When I worked on Mac OS X in the lab I was able to get the terminal colors from using Terminal (rather than X11) and then editing the profile (from the Mac menu bar). The interface is a bit odd on the colors, but you have to set the modified theme as default.
If you see the screenshot, obviously the colors is enabled for terminal. And, if I call echo, it doesn't colorize the result, but if I use echo -e, it colorizes. I checked manual page of echo, and -e means enable interpretation of backslash escapesHow can I enable this option for PHP CLI?
In this post, you will learn how to add some colors to your terminal which is black and white by default in some distros such as Arch Linux. It is not pleasant to the eye especially to newcomers. It may not seem important, but adding some color to the terminal can greatly improve the user experience.
The package will auto-detect whether your terminal can use colors and enable/disable accordingly. When colors are disabled, the color functions do nothing. You can override this with a command-line flag:
TERMCAP is a list of colon-seperated capabilities for the current terminal. Newer distros prefer to use a system-wide terminfo database, which allow applications to lookup, say, xterm-256color (the name of a terminal) though an API and discover it's full list of capabilities; including that it supports 256-colors.
To go back a page in this example, delete the linux part of the URL. You're taken to a new location, the parent directory, containing a different file for you to view. Because this happens inside your web browser, you probably don't think of it as navigating a computer, but you use the same principle in a Linux terminal.
Linux interactive terminals (aka ssh terminal, konsole or console login) automatically choose colors for 'files', 'directories', 'hard links', 'soft links', 'pipes', 'sockets', 'filesystems', etc. You see these colors displayed when you type 'ls' to list file contents. Directories are usually blue, files are usually light grey. Different foreground/background colors are used for various kinds of filesystem objects.
Assuming you're using gnome-terminal, you can select Edit > Profiles... and select the profile that's current (e.g. Default) and click Edit (or click New and enter the name of a new profile - if you do this then you'll need to later set it as the "Profile used when launching a new terminal"). Now you can click on the Colors tab where you can set the background and foreground colors and manipulate the color palette (including selecting among built-in schemes).
To debug color palette problems, tput colors may be useful to see the number of colors in terminfo for a terminal. Fish launched as fish -d term_support will include diagnostic messages that indicate the color support mode in use.
The set_color command uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and incomplete terminfo databases, and lack color information for terminals that support it. Fish assumes that all terminals can use the [ANSI X3.64]( _escape_code) escape sequences if the terminfo definition indicates a color below 16 is not supported.
Most terminals, apart from the basic set of 8 colors, also support the "bright" or "bold" colors. These have their own set of codes, mirroring the normal colors, but with an additional ;1 in their codes:
The Windows Console did not support ANSI escape sequences, nor did Microsoft provide any method to enable them. Some replacements or additions for the console window such as JP Software's TCC (formerly 4NT), Michael J. Mefford's ANSI.COM, Jason Hood's ANSICON[20] and Maximus5's ConEmu interpreted ANSI escape sequences printed by programs. A Python package named colorama [21] internally interpretes ANSI escape sequences in text being printed, translating them to win32 calls to modify the state of the terminal, to make it easier to port Python code using ANSI to Windows. Cygwin performs similar translation to all output written to the console using Cygwin file descriptors, the filtering is done by the output functions of cygwin1.dll, to allow porting of POSIX C code to Windows.
In 2016, Microsoft released the Windows 10 version 1511 update which unexpectedly implemented support for ANSI escape sequences, over two decades after the debut of Windows NT.[22] This was done alongside Windows Subsystem for Linux, allowing Unix-like terminal-based software to use the sequences in Windows Console. This defaults to off, but Windows PowerShell 5.1 enabled it. PowerShell 6 made it possible to embed the necessary ESC character into a string with `e.[23]
As "true color" graphic cards with 16 to 24 bits of color became common, applications began to support 24-bit colors. Terminal emulators supporting setting 24-bit foreground and background colors with escape sequences include Xterm,[29] KDE's Konsole,[49][50] and iTerm, as well as all libvte based terminals,[51] including GNOME Terminal.[citation needed]
This option controls color output (using terminal escape sequences). yes enables colors, no disables them, auto only produces colors when standard output is directed to a terminal. The default value is auto.
The terminal-colors.d functionality is currently supported by all util-linux utilities which provides colorized output. For more details always see the COLORS section in the man page for the utility.
I have seen several options on the web on how to adjust colors but some, albeit very good ones, make me uncomfortable with the type of installations that have to be performed in order to enable these themes.
By default, color.ui is set to auto which will apply colors to the immediate terminal output stream. The auto setting will omit color code output if the output stream is redirected to a file or piped to another process.
IPython uses colors for two main groups of things: prompts andtracebacks which are directly printed to the terminal, and the objectintrospection system which passes large sets of data through a pager.
It's a pity that most programs don't enable colours automatically when available,requiring the user to explicitly configure them to do so.Though I am starting to notice newer commands like "htop" for example use colours by defaultwhen possible, which is a much more sensible approach given the capabilities of terminals today.
This crate provides a cross platform abstraction for writing colored text toa terminal. Colors are written using either ANSI escape sequences or bycommunicating with a Windows console. Much of this API was motivated by useinside command line applications, where colors or styles can be configuredby the end user and/or the environment.
When you try to set the colorscheme of your terminal based editors, colors looked pretty strange. Because our terminal supported 8 bit colors only while we were trying to set 256 colors in the terminal.
If you get the result of tput colors as 256 then voila! your system already has 256 color terminal otherwise if you get something less than 256 then you need some work to Enable 256 Color Terminal.
On many systems, NetHack can display monsters, objects and dungeon features in color, in ASCII mode. The exact appearance of these colors depends on many things, including the platform NetHack was compiled for, compile-time options, run-time options, your terminal settings and the monitor you're using. If your NetHack supports color output, it can be toggled on or off using the color option.
When playing without tiles, you can adjust the colors used by your terminal/console. For example, if dark blue on black background is nearly invisible, try changing the dark blue color in your console color settings.
On systems where NetHack outputs text to be displayed in a terminal (rather than handling text rendering by itself), the internal color codes defined in color.h are mapped to ANSI escape codes or equivalent codes defined in the system terminfo. This mapping is specified in win/tty/termcap.c, and (for a mapping of 16 to 16 colors) is surprisingly platform-dependent. Notable quirks include:
On some systems, NetHack directly maps the 16 internal color codes to RGB colors. On others, this task is left for the terminal emulator, while on some (mainly older) systems, the color choices may even be determined by the graphics hardware. 2ff7e9595c
