Could somebody please provide the code to do the following:
Assume there is a directory of files, all of which need to be run through a program. The program outputs the results to standard out. I need a script that will go into a directory, execute the command on each file, and concat the output into one big output file.
For instance, to run the command on 1 file:
$ cmd [option] [filename] > results.out
The following bash code will pass $file to command where $file will represent every file in /dir
for file in /dir/* do cmd [option] "$file" >> results.out done
el@defiant ~/foo $ touch foo.txt bar.txt baz.txt el@defiant ~/foo $ for i in *.txt; do echo "hello $i"; done hello bar.txt hello baz.txt hello foo.txt
