Full Discussion: File name change with sed

Another solution.
The substitution for the two digit is straight forward;
a second substitution cares about the one digit.
Code:
ls *.txt | sed '
s/\(.*_\)S\([0-9][0-9]_\)\(.*\)/mv & MID-\2\1\3/
s/\(.*_\)S\([0-9]_\)\(.*\)/mv & MID-0\2\1\3/
'

You can put a t command after the first substitution, then, if successful, the second substitution will be skipped.
Code:
ls *.txt | sed '
s/\(.*_\)S\([0-9][0-9]_\)\(.*\)/mv & MID-\2\1\3/
t
s/\(.*_\)S\([0-9]_\)\(.*\)/mv & MID-0\2\1\3/
'

re-pcr

RE-PCR(1)						      General Commands Manual							 RE-PCR(1)

NAME

       re-PCR -- Find sequence tagged sites (STS) in DNA sequences

SYNOPSIS

       re-PCR [-hV] -p hash-file [-g gaps] [-n mism] [-lq] [primer ...]

       re-PCR [-hV] -P hash-file [-g gaps] [-n mism] [-l] [-m margin] [-O+|-] [-C batchcnt] [-o outfile] [-r+|-] [primers-file ...]

       re-PCR [-hV] -s hash-file [-g gaps] [-n mism] [-lq] [-m margin] [-o outfile] [-r+|-] [left right lo[-hi] [...]]

       re-PCR [-hV] -S hash-file [-g gaps] [-n mism] [-lq] [-m margin] [-O+|-] [-C batchcnt] [-o outfile] [-r+|-] [stsfile ...]

DESCRIPTION

       Implements reverse searching (called Reverse e-PCR) to make it feasible to search the human genome sequence and other large genomes by per-
       forming STS and primer searches.

OPTIONS

       -p=hash-file
		 Perform primer lookup using hash-file

       -P=hash-file
		 Perform primer lookup using hash-file

       -s=hash-file
		 Perform STS lookup using hash-file

       -S=hash-file
		 Perform STS lookup using hash-file

       -n=mism	 Set max allowed mismatches per primer for lookup

       -g=gaps	 Set max allowed indels per primer for lookup

       -m=margin Set variability for STS size for lookup

       -l	 Use presize alignments (only if gaps>0)

       -G	 Print alignments in comments

       -d=min-max
		 Set default STS size

       -r=+|-	 Enable/disable reverse STS lookup

       -O=+|-	 Enable/disable syscall optimisation

       -C=batchcnt
		 Set number of STSes per batch

       -o=outfile
		 Set output file name

       -q	 Quiet (no progress indicator)

EXAMPLE

	famap -tN -b genome.famap org/chr_*.fa

	fahash -b genome.hash -w 12 -f3 ${PWD}/genome.famap

	re-PCR -s genome.hash -n1 -g1 ACTATTGATGATGA AGGTAGATGTTTTT 120-200
