at command in rc script with parms

[Scott Lindstrom_2]

I want to have one of my rc scripts use the "at now + 5 minutes" syntax, but the problem I have is the file to be executed has a parm:

case $1 in

'start')
su - appuser -c "/bin/at -f /usr/bin/application start now + 5 minutes"


This command fails with the message "bad time specification" I think because it believes the word 'start' should be the time specification. (If I take 'start' out the syntax is OK but obviously this is not what I want).

I can make this work if I make an entirely new script that just does the "/usr/bin/application start" but I an trying to avoid that.

I have tried a hereis document but could not get that to work in a rc script.

Any ideas on how to make this work?

Hi Scott:

Why? Afterall, a wrapper script is often used to supply default arguments. It's a minor bit of indirection for infrequent use here.

Hi,

you can create the temporary script on the fly, including a self-cleanup, if '/usr/bin/application' has execute rights:

case $1 in

'start')
echo "/usr/bin/application start
ret=\$?
rm -f /tmp/start_app$$
exit \$ret" >/tmp/start_app$$
su - appuser -c "/bin/at -f /tmp/start_app$$ now + 5 minutes"

Obviously the correct way to handle it is to encode the parm in the script, and exec the real one. Or what Peter suggests.

Another way is to symlink multiple scripts to one and look at $0 to determine if this is "start" or what.

Thanks everyone for their replies; I went with using a second script.
