Check These Out

Generate MD5 hash for a string

move a lot of files over ssh
copy files to a ssh server with gzip compression

print all except first collumn

list block devices
Shows all block devices in a tree with descruptions of what they are.

add all files not under version control to repository
With the force options the same results can be achieved

check open ports (both ipv4 and ipv6)
While `lsof` will work, why not use the tool designed explicitly for this job? (If not run as root, you will only see the names of PID you own)

Restrict the bandwidth for the SCP command
the command is obvious, I know, but maybe not everyone knows that using the parameter "-l" you can limit the use of bandwidth command scp. In this example fetch all files from the directory zutaniddu and I copy them locally using only 10 Kbs

Split File in parts
Split File in 19 MB big parts, putting parts together again via cat Nameforpartaa Nameforpartab Nameforpartac >> File

Batch rename extension of all files in a folder, in the example from .txt to .md

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" }
