So you have a group files with an unuseful name for another program or service you are using and you want to rename the whole group.
Here is the solution:
#!/bin/bash # renames.sh # basic file renamer criteria=$1 re_match=$2 replace=$3 for i in $( ls *$criteria* ); do src=$i tgt=$(echo $i | sed -e "s/$re_match/$replace/") mv $src $tgt done
It is used as such:
./renamer.sh csv '201606' '2016-06'
It uses sed and that allows all of the regex you might be familiar with, a la:
I won’t go into heavy regex usage here, there are several good articles/guides out there on that. One day I might post a conglomeration of those with most used by myself at the top with any additional items I’ve found that are helpful.
Also, I definitely found this and copied it verbatim from: http://tldp.org/HOWTO/Bash-Prog-Intro-HOWTO-12.html which is a great resource for anyone wanting to expand their knowledge/skills on a well organized knowledge system. Thank you TLDP, you’ve been a great resource for years to date. ^_^
