curl as a variable breaks the script

The following variable was being used in a bash script;

CURL="curl -o /dev/null -u "$USERNAME:$PASSWD" --connect-timeout 5 -X POST"

Then, in my script, I would use the following;

$CURL -F function=clean_reports $SERVER_URL/myapp.php

I found that curl wasn't sending anything to php until I removed the variable and turned each curl line into the following;

 curl -o /dev/null  -u "$USERNAME:$PASSWD" --connect-timeout 5 -X POST -F function=clean_reports $SERVER_URL/myapp.php

Why? And how can I use this variable to shorten my lines?

Hi,

I assume that the variables USERNAME and PASSWD are not yet filled when the CURL variable is set.

This will lead to a command "$CURL" looking like this:

curl -o /dev/null -u :  --connect-timeout 5 -X POST

which is certainly not correct. The content of CURL will stay the same even if the variables are filled later in the script before running "$CURL ... ..."

So either fill both variables USERNAME and PASSWD before setting CURL, or, if this is not possible,
you should try this:

CURL='curl -o /dev/null -u "$USERNAME:$PASSWD" --connect-timeout 5 -X POST'

Please note the single quotes!

Later in the script, once the required variables are filled run:

eval $CURL ... ...

Should have caught that myself. Yes, the username and password were AFTER the variable.

Thanks for the help, all fixed now.
