Question How to run this program with only one input file at a time

i have a program ABC, which runs every two minutes and takes the input according to the a value called "pointer"

files need to be processed by ABC are

input0001
input0002
input0003
input0004
input0005

current value of pointer is 0001, now program runs and takes all the files from input0001 onwards and processes all till input0005.

i want to process only one file in each run of this program, instead of all in single run.

i have only the right to rename the input files and process them one by one. if i'll make input0002 to input0002.stop , program will stop, but how to resume it back, and rename all files one by one. i cant make any change in the program. plz help

NAME
rename - renames multiple files SYNOPSIS
rename [ -v ] [ -n ] [ -f ] perlexpr [ files ] DESCRIPTION
"rename" renames the filenames supplied according to the rule specified as the first argument. The perlexpr argument is a Perl expression which is expected to modify the $_ string in Perl for at least some of the filenames specified. If a given filename is not modified by the expression, it will not be renamed. If no filenames are given on the command line, filenames will be read via standard input. For example, to rename all files matching "*.bak" to strip the extension, you might say rename 's/.bak$//' *.bak To translate uppercase names to lower, you'd use rename 'y/A-Z/a-z/' * OPTIONS
-v, --verbose Verbose: print names of files successfully renamed. -n, --no-act No Action: show what files would have been renamed. -f, --force Force: overwrite existing files. ENVIRONMENT
No environment variables are used. AUTHOR
Larry Wall SEE ALSO
mv(1), perl(1) DIAGNOSTICS
If you give an invalid Perl expression you'll get a syntax error. BUGS
The original "rename" did not check for the existence of target filenames, so had to be used with care. I hope I've fixed that (Robin Barker). perl v5.12.4 2011-08-10 RENAME(1)
