Check These Out

bash script to zip a folder while ignoring git files and copying it to dropbox
Better tool for exporting git's repository is Git itself!

Reset hosed terminal,
stty sane resets the tty to basic usable function. The ^J is a newline -- sometimes CR/LF interpretation is broken so use the ^J explicitly.

Fibonacci numbers with awk
Another combination of seq and awk. Not very efficient, but sufficiently quick.

Using a single sudo to run multiple && arguments
Bash's here string

Securely stream (and save) a file from a remote server
Securely stream a file from a remote server (and save it locally). Useful if you're impatient and want to watch a movie immediately and download it at the same time without using extra bandwidth. This is an extension of snipertyler's idea. Note: This command uses an encrypted connection, unlike the original.

Convert seconds to [DD:][HH:]MM:SS
Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

Slightly better compressed archives
Avoids creating useless directory entries in archive, and sorts files by (roughly) extension, which is likely to group similar files together for better compression. 1%-5% improvement.

Send e-mail if host is 'dead' or not reachable
Cleaner with a mailto assignment in crontab (if the command fails you get an email): MAILTO=admin@example.com 10,30,50 * * * * ping -q -c1 -w3 192.168.0.14 >/dev/null

Configuring proxy client on terminal

Parse a quoted .csv file
The $2, $3, $4 fields are arbitrary but note that the first field starts from $2 and the last field is $NF-1. This is due to the fact that the leading and trailing quotes are treated as field delimiters.
