Stripping ^M at end of each line for files

list block devices

Multiple variable assignments from command output in BASH

It's quite easy to capture the output of a command and assign it in a shell's variable: $ day=$(date +%d) $ month=$(date +%m) But, what if we want to perform the same task with just one program invocation? Here comes the power of eval! date(1) outputs a string like "day=29; month=07; year=11" (notice the semicolons I added on purpose at date's custom output) which is a legal shell line. This like is then parsed and executed by the shell once again with the help of eval. Just setting 3 variables! Inspired by LinuxJournal's column "Dave Taylor's Work the Shell".

search user defined function in c language

list all file extensions in a directory

Works on current directory, with built-in sorting.

Copy without overwriting

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

find largest file in /var

grep (or anything else) many files with multiprocessor power

Parallel does not suffer from the risk of mixing of output that xargs suffers from. -j+0 will run as many jobs in parallel as you have cores. With parallel you only need -0 (and -print0) if your filenames contain a '\n'. Parallel is from https://savannah.nongnu.org/projects/parallel/

Make vim open in tabs by default (save to .profile)

I always add this to my .profile rc so I can do things like: "vim *.c" and the files are opened in tabs.
