Shell Programming and Scripting

Hi,

I have file with format

Code:

abcd.gz.20151011.1

, i need to rename as

Code:

abcd.gz.20151011

.we can use move command for one file. How to change multiple files.

Adapt to suit your requirement:

Code:

for file in /dir/filepattern*
do
    name_before_last_period=${file%\.*}
    mv $file ${name_before_last_period}
done

Hello nag_sathi,

Could you please try following and let me know if you have queries.

Code:

for file in abcd.gz.*
do
 echo mv $file ${file%\.*}
done

Above will check for all files like abcd.gz.* if you want to check all .gz files then following may help in same.

Code:

for file in *.gz.*
do
 echo mv $file ${file%\.*}
done

Also remove echo in above solutions if you are happy with results then it will rename them once you remove it.

NOTE: Also you should run this in the directory where you have files, else you could mention complete path like /path/to/files/*.gz.* or /path/to/files/abcd.gz.*.


Thanks,
R. Singh

Note: the backslash escape before the dot (\.) is not necessary since this is not regex and the dot does not have a special meaning.
