Subject: help with 'rename' function
Date: Fri, 12 Jun 98 04:15:57 -0400 [thread overview]
Message-ID: <199806120816.EAA22173@luomat.peak.org> (raw)
I used to have a binary that did this, but I've lost it.
What it did was simple: it changed extensions of filenames.
For example, say you have a bunch of files which ended with .THIS and you
wanted to change them to end with .THAT
You would do
rename *.THIS THIS=THAT
and it would go on its way... or if it was just one file:
rename foo.THIS THIS=THAT
I've tried to make a function which does this, but it fails:
(the $others variable is ALL the file names rather than cycling through one by one)
rename () {
local i last oldext newext short new others
last=`echo $* | awk '{print $NF}'`
# all the args except the last one
others=`echo $* | sed "s/ $last$//g"`
oldext=`echo $rename | tr -s '=' ' ' | awk '{print $1}'`
newext=`echo $rename | tr -s '=' ' ' | awk '{print $2}'`
echo "oldext is $oldext"
echo "newext is $newext"
for i in $others
do
short=`echo $i .$oldext`
new=`echo $short.$newext`
mv $i $new
done
}
