Hi!

 

I need help writing a rename script that will not disturb double digit numbers in the file name.

 

Lets say I have the following files in a folder:

 

mandriva01.jpg

suse22.jpg

fedora40.jpg

 

And I want to rename all of them to:

 

linux01.jpg

linux22.jpg

linux40.jpg

 

How would I do it? I am having trouble with the double digit numbers.

 

Here's the base script that will only work with single digit.

#!/bin/sh
for I in `ls`; do
if echo $I | grep -q '^[0-9]\.jpg'; then
mv $I linux$I
fi; done

What do I have to modify to make it double digits? I tried using if echo $I | grep -q '^[0-9][0-9]\.jpg' but didn't work.

 

please. Thanks in advance.

Try this. It takes any file that ends in xx.jpg (where xx is any two digits) and renames it to linux followed by the filename stripped of the first series of alpabetic chars up to the first digit.

 

It should work for the examples you gave - for example:

 

Original filename: mandriva01.jpg

Renamed file: linux01.jpg

 

There are probably more elegant ways to do this, but this should work.

 

#!/bin/sh
for I in `ls`; do
if echo $I | grep -q '[0-9][0-9]\.jpg$'; then
  mv $I linux`echo $I | sed 's/^[a-zA-Z]*//'` >/dev/null
fi; done

 

Note, however, that if the filename has any numeric digits embedded in the alpha characters before the final xx.jpg, this won't work right, as shown below:

 

Example: mand01driva12.jpg

Renamed file: linux01driva12.jpg
