Commands tagged highlight (7)

  • Nobody wants the boss to notice when you're slacking off. This will fill your shell with random data, parts of it highlighted. Note that 'highlight' is the Perl module App::highlight, not "a universal sourcecode to formatted text converter." You'll also need Term::ANSIColor. Show Sample Output


    1
    cat /dev/urandom | hexdump -C | highlight ca fe 3d 42 e1 b3 ae f8 | perl -MTime::HiRes -pne "Time::HiRes::usleep(rand()*1000000)"

    perl -MText::Highlight -E '$h=Text::Highlight->new(ansi=>1); my $text=do{local $/; open my $fh, "<", $ARGV[0]; <$fh>}; say $h->highlight("Perl", $text);' path/to/perl-file.pl

  • 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; }

Poor's man Matrix script
This creates a matrix of letters that run forever until you hit Ctrl-C simulating "The Matrix" effect... just for fun :) You may want to try the -n and -y switch to change the "FX" LOL! e.g.: pwgen -ny 3

Detect illegal access to kernel space, potentially useful for Meltdown detection
Based on capsule8 agent examples, not rigorously tested

Creates a 'path' command that always prints the full path to any file
The command creates an alias called 'path', so it's useful to add it to your .profile or .bash_profile. The path command then prints the full path of any file, directory, or list of files given. Soft links will be resolved to their true location. This is especially useful if you use scp often to copy files across systems. Now rather then using pwd to get a directory, and then doing a separate cut and paste to get a file's name, you can just type 'path file' and get the full path in one operation.

list files recursively by size

awk date convert
Convert readable date/time with `date` command

backup a directory in a timestamped tar.gz
creates a tar.gz with a name like: backup20090410_173053.tar.gz of a given directory. this file was made 10 April 2009 at 5:30:53pm see date's man page to customize the timestamp format

Print just line 4 from a textfile
Prints the 4th line and then quits. (Credit goes to flatcap in comments: http://www.commandlinefu.com/commands/view/6031/print-just-line-4-from-a-textfile#comment.)

Change timestamp on a file
-a for access time, -m for modification time, -c do not create any files, -t timestamp
