[SOLVED] Copy a file with mktemp as destination?

mprowe · 03-26-2024, 06:14 AM

I'd like a one-line (that I can put in my crontab), something like this?

$ cp <sourcefile> <mktemp -p /sms sourcefile_XXXXXX>

Regards, Martin

better to put it into a script and run that script from crontab.

Code:

 cp <sourcefile> $(mktemp -p /sms sourcefile_XXXXXX)

or something similar may work

You ought to wrap that in a script.

Code:

#!/bin/sh

PATH=/usr/local/bin:/usr/bin:/bin

set -e

p=sms
test -e /tmp/${p} || mkdir -p /tmp/${p}
test -d /tmp/${p}

dst=$(mktemp -p ${p} -d sourcefile_XXXXXX)
src=somesourcefile

cp -p ${src} ${dst}

As a one-liner it would still be using command substitution.

Code:

cp -p somesourcefile $(mktemp -p sms -d sourcefile_XXXXXX)

The way you have it set, the directory /tmp/sms/ must exist before running mktemp because mktemp won't create it for you.
