Commands tagged color (58)

  • Highlight the plain text in XML (or HTML, SGML, etc)

    Don't want to open up an editor just to view a bunch of XML files in an easy to read format? Now you can do it from the comfort of your own command line! :-) This creates a new function, xmlpager, which shows an XML file in its entirety, but with the actual content (non-tag text) highlighted. It does this by setting the foreground to color #4 (red) after every tag and resets it before the next tag. (Hint: try `tput bold` as an alternative). I use 'xmlindent' to neatly reflow and indent the text, but, of course, that's optional. If you don't have xmlindent, just replace it with 'cat'. Additionally, this example shows piping into the optional 'less' pager; note the -r option which allows raw escape codes to be passed to the terminal. Show Sample Output


    0
    xmlpager() { xmlindent "$@" | awk '{gsub(">",">'`tput setf 4`'"); gsub("<","'`tput sgr0`'<"); print;} END {print "'`tput sgr0`'"}' | less -r; }

  • Print all 256 colors for testing TERM or for a quick reference

    Basically, \033[ is a semi-portable unix escape character. It should work in linux, osx, bsd, etc. The first option is 38. This tells whatever is interpreting this (and this is merely convention) that a special color sequence follows. The next option is 5 which says that the next option will specify a color ? {0..256} of course. These options, as you can see, are separated by a single `;` and the entire escape sequence is followed by a mandatory `m`. The second escape sequence (following "COLOR") is simply to clear all terminal attributes (for our purposes, it clears color). This for loop is helpful for testing all 256 colors in a 256 console (note: this will not work in a standard Linux tty console) or to see which number corresponds to which color so that perhaps you can use it!

    for i in {0..256}; do echo -e "${i} \033[38;05;${i}m COLOR \033[0m"; done
