Check These Out

Two command output
Summarize established connections after netstat output. Using tee and /dev/stderr you can send one command output to terminal before executing wc so you can summarize at the bottom of the output.

Filter out all blank or commented (starting with #) lines

Convert all files *.mp4 to *.mpeg using ffmpeg (Windows Cmd line)
Note: %~nI expands %I to a file name only (cf. http://technet.microsoft.com/en-us/library/bb490909.aspx)

List only directories, one per line

Show all current listening programs by port and pid with SS instead of netstat

Collect a lot of icons from /usr/share/icons (may overwrite some, and complain a bit)
Today I needed to choose an icon for an app. My simpler way: put all of /usr/share/icons in myicons folder and brows'em with nautilus. Then rm -r 'ed the entire dir.

Put split files back together, without a for loop
After splitting a file, put them all back together a lot faster then doing $cat file1 file2 file3 file4 file5 > mainfile or $for i in {0..5}; do cat file$i > mainfile; done When splitting, be sure to do split -d for getting numbers instead of letters

Print all fields in a file/output from field N to the end of the line

Sort file greater than a specified size in human readeable format including their path and typed by color, running from current directory
1. find file greater than 10 MB 2. direct it to xargs 3. xargs pass them as argument to ls

Fibonacci numbers with awk
recursive version, "pure" AWK
