OSXFAQ Mac OS X UNIX Tip-of-the-Day
Scripting One-Liners - Batch Process Files
Here's a handy way to process every file in a directory:
$ for f in *; do echo "File: $f"; done
File: a file with spaces.txt
File: db-snmpd.conf
File: snmp.conf
File: snmp.txt
File: snmpd.conf
File: treewalk-dot
$
(A more useful example would do something more than simply echo each filename.) It'll even cope with filenames that contain spaces, as witnessed by the first file in the list.
You can process each field in a file with:
$ for f in $(cat file-to-process); do echo $f; done
Visit the Site of the Book of the Unix Tips:
Projects 58 and 83 cover the batch-processing of files using both Bash functions and Bash shell scripts.
