Perl Command Line Question

i'm trying automate process, running few problems.

have program running following command:

code:

./program -in file_001.txt -out file_001

where reading in in file, , outputting files end filename.

need around 90 different files (up file_088.txt).

i'm trying put perl script run them in command line, 1 @ time, incrementing filename reads in, , makes sure that equal out name.

code:

  for($f=1;$f<=88;f++){  './program -in file_0$f.txt -out file_0$f'  }  

something wrong, , i'm not sure how make sure 1,2,3,4,5,6,7,8,9 listed '01,02,...,09' make naming scheme work properly.


thanks!

 

this kind of thing quite easy shell script. there particular reason need/want use perl?

edit: if bash ok can start here:

code:

for file in *.txt; echo -in $file -out ${file%.*} ; done
