change file names

[Brian Lee_4]

I have 100 files starting with sla in one directory.
I want to change those files starting with sap.

How can I do it?

[Mark Grant · Accepted solution]

Somthing like

for i in 'ls sla*'
do
$base=`expr "$i" : "sla\(.*\)"`
mv $i "sap$base"
done

Test this first using "cp" instead of "mv" if you're nervous :)

Hi,

Here is one way to do it:

for f in sla*
do
t=sap${f#sla}
mv $f $t
done

Hi Brian,

for FILE in sla*
do
NEWFILE=`expr "${FILE}" : "sla\(.*\)"
mv ${FILE} "sap${NEWFILE}"
done

greetings,

cd to the directory and run this:

for _FILE in `ls ./sla*`; do
_NEW_FILE=`echo $_FILE|sed -e s/sla/sap/`
mv $_FILE _NEW_FILE
done

#!/bin/sh

or fln in `ls sla*`
do
newfln=$(echo $fln | cut -c4-)
newfln="sap"${newfln}
echo $fln $newfln
done

change echo with mv
you may want to check file existence beforehand
