Generate SHA1 hash for each file in a list
All output is placed in file SHA1SUMS which you can later check with 'sha1sum --check'. Works on most Linux distros where 'sha1sum' is installed.

Determine status of a RAID write-intent bitmap
Report information about a bitmap file.

Matrix Style
I like the fact the Patola's version uses only ones and zeros, but I also like the sparse output of the other versions. This one combines both of those features and eliminates some unnecessary cruft. You can vary the sparseness by changing "$(($RANDOM % 5))" to another number. The number in this term "$(($RANDOM % 4))" controls how frequently the numbers are output bold.

Rename files in batch

Execute multiple commands from history
Assuming that 219,229 and 221 are entries in history, I recall them in a single line for execute multiple commands 219 ifdown wlan0 ... 221 ifup wlan0 ... 229 iwconfig wlan0 mode Managed so the result is execution of # ifdown wlan0 ; iwconfig wlan0 mode Managed ; ifup wlan0

Change the ownership of all files owned by one user.
Finds all files in /home owned by UID 1056 and changes to 2056.

Search files with js declarations inside
Useful to crawl where the javascript is declared, and extract it a common file. You can redirect it to a file to review item by item.

List .log files open by a pid
Uses lsof to display the full path of ".log" files opened by a specified PID.

generate random password
-B flag = don't include characters that can be confused for other characters (this helps when you give someone their password for the first time so they don't cause a lockout with, for example, denyhosts or fail2ban) -s flag = make a "secure", or hard-to-crack password -y flag = include special characters (not used in the example because so many people hate it -- however I recommend it) "1 10" = output 1 password, make it 10 characters in length For even more secure passwords please use the -y flag to include special characters like so: $ pwgen -Bsy 10 1 output>> }&^Y?.>7Wu

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" }
