[Solved] Modifying/Removing Timestamps from a filename
So given filenames of varying lengths, I was wondering how I would remove or modify appended timestamps of the current date DD-MM-YY.

So say:
Code:
test_DD-MM-YY.txt
coolbeans_DD-MM-YY.pdf

And what I expect the output to be:
Code:
test.txt
coolbeans.pdf

Thanks Smilie

Perhaps the following examples will help:
Code:
#!/bin/ksh
for infile in test_DD-MM-YY.txt coolbeans_DD-MM-YY.pdf
do      printf "infile:\t\t%s\n" "$infile"
        # Following will work with recent bash and ksh:
        outfile=${infile/_????????/}
        printf "outfile:\t%s\n" "$outfile"
        # Following will work with any POSIX conforming shell:
        Poutfile=${infile%_*}.${infile#*.}
        printf "POSIX outfile:\t%s\n\n" "$Poutfile"
done

which produces the output:
Code:
infile:		test_DD-MM-YY.txt
outfile:	test.txt
POSIX outfile:	test.txt

infile:		coolbeans_DD-MM-YY.pdf
outfile:	coolbeans.pdf
POSIX outfile:	coolbeans.pdf
