I found this command on a different site and thought you guy might enjoy it. Just change "YOURSEARCH" to what ever you want to search. Example, "Linux Commands"

Puts every word from a file into a new line
Basically it creates a typical word list file from any normal text.

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" }

updatedb for MAC OSX
MAC OSX doesn't come with an updatedb command by default, this will emulate the updatedb thats on a typical Linux OS. Simply add it to your ~/.bash_profile

Print entire field if string is detected in column
It searches for a specific value in the specified column and if it finds it it'll print the whole field/row. Similarly, if you don't know what you're looking for exactly but want to exclude something you're already aware of, you can exclude that "something: awk '{ if ($column != "string") print $0}'

Replace 'csv_file.csv' with your filename.

- grep for the word in a files, use recursion (to find files in sub directories), and list only file matches -| xargs passes the results from the grep command to sed -sed -i uses a regular expression (regex) to evaluate the change: s (search) / search word / target word / g (global replace)

Use date to find the date at other days and times.
