Simple Gumblar check command

View all new log messages in real time with color
This will show all changes in all log files under /var/log/ that are regular files and don't end with `gz` nor with a number

type partial command, kill this command, check something you forgot, yank the command, resume typing.
Example : $ vim /etc/fstab ## damn $ $ sudo ## like a boss. Example 2 : $ sudo vim /root/bin/ ##uh... autocomplete doesn't work... $ $ sudo ls /root/bin ##ah! that's the name of the file! $ sudo vim /root/bin/ ##resume here! Thanks readline!

Generate random valid mac addresses
Doubt it actually generates valid mac addresses but this version doesn't need any external commands so it runs much faster. Much shorter as well.

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" }

Puts every word from a file into a new line
Simply translates whitespace to newlines. Could be enhanced to compress out extra newlines, but that might be better handled in the next tool down the pipe, with eg uniq(1).

Archive all files that have not been modified in the last days
Finally, we can make the file "unchangeable" sudo chattr +i

Merge some PDF files into a single one

Count the number of queries to a MySQL server
