Top Forums Shell Programming and Scripting Have a shell script check for a file to exist before processing another file Post 302096083 by heprox on Monday 13th of November 2006 10:33:51 PM

You lost me....

Forgive my ignorance, so how would bracketing the "-a" work?

Code:
[[ -a /gers/genret/tmp/poll_$fileExtension.txt  ]] && continue

...it would check for the file "poll_" and if it found it stop there and move onto the next file? I'm confused how this works?

NAME
service - run a System V init script SYNOPSIS
service SCRIPT COMMAND [OPTIONS] service --status-all service --help | -h | --version DESCRIPTION
service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working directory set to /. The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the invoked script, service passes COMMAND and OPTIONS it to the init script unmodified. All scripts should support at least the start and stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start command. service --status-all runs all init scripts, in alphabetical order, with the status command. EXIT CODES
service calls the init script and returns the status returned by it. FILES
/etc/init.d The directory containing System V init scripts. ENVIRONMENT
LANG, TERM The only environment variables passed to the init scripts. SEE ALSO
/etc/init.d/skeleton, update-rc.d(8), init(8), invoke-rc.d(8). Jan 2006 service(8)
