Very simple shell script needed for automatisation, please help
I need a script which would rename bunch of files. For example:
file1
file2
....
file20
need to be renamed
newname1
newname2
.....
newname20
Part of the filename needs to be changed and keep thee numbers, I know can be done with sed, dont get it.
Numbers are not always from 1, it can be
file45
file46 etc.
Can somebody help me please?
