filename change in Linux

Question

I am quite new to awk and linux scripting. Need your help to modify the file generation:

Current output: A20211126.0200+0500-0215+0500.xml

Expected output: A20211126.0200-0215.xml

for all the files in a particular directory.

I want to use a crontab as well to ensure the file names with +0500 is checked and if found then convert the same as mentioned in the expected output.

Thanks All.

I did the following to achieve the desired output.

for file in *.xml ; do mv $file ${file//+0500/} ; done

now I am able to remove the +0500 part

Answer 1

If you have perl prename available, then you can use rename to achieve this with regex.

If it is not available, you can install it via perls cpan (similar to pip) and then replace util-linux version that should be installed by default.

Perl will need to be available to use CPAN

$ ls
A20211126.0200+0500-0215+0500.xml
$ rename 's/([^+]*)[^-]*([^+]*)[^.]*(.*)/$1$2$3/' *.xml
$ ls
A20211126.0200-0215.xml
