Bash - Redirection with wildcards

Question

I\'m testing to do redirection with wildcards. Something like:

./TEST* < ./INPUT* > OUTPUT

Anyone have any recommendations? Thanks.

Answer 1

There is a program called TEST* that has to get various redirection into into called INPUT*, but the thing is there are many TEST programs and they all have a different number, e.g. TEST678. What I'm trying to do is push all the random INPUT files into all the all TEST programs.

You can write:

for program in TEST*            # e.g., program == 'TEST678'
do
  suffix="${program#TEST}"      # e.g., suffix == '678'
  input="INPUT$suffix"          # e.g., input == 'INPUT678'
  "./$program" < "$input"       # e.g., run './TEST678 < INPUT678'
done > OUTPUT
