Better use iproute2 !
This is a dirty raw way to simply list ELF objects in a folder.
The output is ready to be parsed i.e to the stripper or what else needs a path to an ELF object.
If you need to randomize the lines in a file, but have an old sort commands that doesn't support the -R option, this could be helpful. It's easy enough to remember so that you can create it as a script and use that.
It ain't real fast. It ain't safe. It ain't super random. Do not use it on untrusted data. It requires bash for the $RANDOM variable to work.
HP UX doesn't have a -a switch in the ifconfig command.
This line emulates the same result shown in Solaris, AIX or Linux
If a directory name contains space xargs will do the wrong thing. Parallel https://savannah.nongnu.org/projects/parallel/ deals better with that.
xargs deals badly with special characters (such as space, ' and "). In this case if you have a file called '12" record'.
Parallel https://savannah.nongnu.org/projects/parallel/ does not have this problem.
Both solutions work bad if the number of files is more than the allowed line length of the shell.
This version makes uses of Bash shell expansion, so it might not work in all other shells.
Somewhat shorter version.

Created on Ubuntu 9.10 but nothing out of the ordinary, should work anywhere with a little tweaking. 5163 is the number of unique first names you get when combine the male and female first name files from. http://www.census.gov/genealogy/www/data/1990surnames/names_files.html
i wanted to delete all duplicate lines from .bash_history and keep the order of the other lines.
the command cat's the file and adds line numbers, then sorts by the second column. afterwards uniq omits repeated lines, but skips the first field (the line number). then it sorts by the line numbers and at the end cuts the numbers off.
Removes all the at shedules jobs
A way not so simple but functional for print the command for the process that's listening a specific port.
I got the pid from lsof because I think it's more portable but can be used netstat
List everyone who committed to a particular project, listed alphabetically. To list by commits, add -n to the shortlog.
Get the line containing "inet addr:" and the line before that, get down to only the first line, and then get the first word on that line, which should be the interface.
eliminates "l" and "o" characters change length by changing 'x' here: cut -c 1-x
The command gives size of all files smaller than 1024k, this information, together with disk usage, can help determin file system parameter (e.g. block size) or storage device (e.g. SSD v.s. HDD).
Note if you use awk instead of "cut| dc", you easily breach maximum allowed number of records in awk.
This reports directly using mtx what Tape is in the mailslot (Import/Export tray) on most autoloaders.
You will need to change /dev/sg13 to your autloader device file and adjust the 63 at the end to your tape label character length(ie 63 for 8 characters 64 for 9 characters)
