List all MAC addresses on a Linux box. sort -u is useful when having virtual interfaces.

Credit goes to brun65i but he posted it as a comment instead as an alternative. I hadn't noticed the -h option on sort before and this seems like the cleanest alternative. Thanks Brun65i!

Show disk space info, grepping out the uninteresting ones beginning with ^none while we're at it.

The main point of this submission is the way it maintains the header row with the command grouping, by removing it from the pipeline before it gets fed into the sort command. (I'm surprised sort doesn't have an option to skip a header row, actually..)

It took me a while to work out how to do this, I thought of it as I was drifting off to sleep last night!

This works by reading in two lines of input, turning each into a list of one-character matches that are sorted and compared.

list top committers (and number of their commits) of svn repository.

in this example it counts revisions of current directory.

awk '{if ($1 ~ /Package/) p = $2; if ($1 ~ /Installed/) printf("%9d %s\n", $2, p)}' /var/lib/dpkg/status | sort -n | tail
for _a in {A..Z} {a..z};do _z=\${!${_a}*};for _i in `eval echo "${_z}"`;do echo -e "$_i: ${!_i}";done;done|cat -Tsv

This uses some tricks I found while reading the bash man page to enumerate and display all the current environment variables, including those not listed by the 'env' command which according to the bash docs are more for internal use by BASH. The main trick is the way bash will list all environment variable names when performing expansion on ${!A*}. Then the eval builtin makes it work in a loop.

I created a function for this and use it instead of env. (by aliasing env).

This is the function that given any parameters lists the variables that start with it. So 'aae B' would list all env variables starting wit B. And 'aae {A..Z} {a..z}' would list all variables starting with any letter of the alphabet. And 'aae TERM' would list all variables starting with TERM.

aae(){ local __a __i __z;for __a in "$@";do __z=\${!${__a}*};for __i in `eval echo "${__z}"`;do echo -e "$__i: ${!__i}";done;done; }

And my printenv replacement is:

alias env='aae {A..Z} {a..z} "_"|sort|cat -v 2>&1 | sed "s/\\^\\[/\\\\033/g"'

cd /proc&&ps a -opid=|xargs -I+ sh -c '[[ $PPID -ne + ]]&&echo -e "\n[+]"&&tr -s "\000" " "<+/cmdline&&echo&&tr -s "\000\033" "\nE"<+/environ|sort'

Grabs the cmdline used to execute the process, and the environment that the process is being run under. This is much different than the 'env' command, which only lists the environment for the shell. This is very useful (to me at least) to debug various processes on my server. For example, this lets me see the environment that my apache, mysqld, bind, and other server processes have.

Here's a function I use:

aa_ps_all () { ( cd /proc && command ps -A -opid= | xargs -I'{}' sh -c 'test $PPID -ne {}&&test -r {}/cmdline&&echo -e "\n[{}]"&&tr -s "\000" " "<{}/cmdline&&echo&&tr -s "\000\033" "\nE"<{}/environ|sort&&cat {}/limits' ); }

Notes:

1) -n-1 means sort key is the last field

2) -l is important if each separate record is on a new line (usually so for text files)

3) -j tells msort not to create log file (msort.log) in the working directory

4) may need to install msort package.

5) msort does lot more. Check man msort

Works in sort (GNU coreutils) 7.4, don't know when it was implemented but sometime the last 6 years.

Another one.

Maybe not the quicker because of the sort command, but it will also look in other man sections.

updated with goodevilgenius 'shuf' idea

All with only one pipe. Should be much faster as well (sort is slow). Use find instead of ls for recursion or reliability.

Edit: case insensitive

If your grep doesn't have an -o option, you can use sed instead.

find /path/to/dir -type f | grep -o '\.[^./]*$' | sort | uniq

Use this BASH trick to create a variable containing the TAB character and pass it as the argument to sort, join, cut and other commands which don't understand the \t notation.

sort -t $'\t' ... join -t $'\t' ... cut -d $'\t' ...
