Curl (bash) command not working in Jenkinsfile groovy script

In my Jenkinsfile Groovy script, I have the following code;

stage('Test the 500 log URLs') 
 steps 
 script 
 echo 'Testing the URLs from the 500 error access log...'
 sh '''#!/bin/bash
 while IFS= read -r line; do
 URL=`echo $line

The first parts of the file work correctly, including the command;

URL=`echo $line | awk 'print $2' | sed 's/http:/https:/' `

However, the following line;

RESULT=`curl -LI $URL -o /dev/null -w "%http_coden" -s | tr -d '[:space:]' `

fails when I run the Jenkins build.

The following error is produced;

line 4: curl: command not found

I can't see why the previous line ran ok, but this line is failing.

Is there something obvious I'm missing?

Any help would be greatly appreciated.

thanks

Does Jenkins actually respect the shebang? (If not, the [[ will probably raise an error.) The mostly likely problem is not with the script itself, but that curl isn't available on the Jenkins host.

Please read the error again: curl: command not found. It's saying that it can't find curl to execute. It's not installed.

It is possible that curl was not installed in a common location like /usr/bin/. I'd suggest you try to run curl via its full path.

$ which curl
/usr/somelocation/curl # <- just an example

Then in your script:

RESULT=`/usr/somelocation/curl -LI $URL...`

Another option is to edit your /etc/profile and append to PATH wherever curl is located.

export PATH=$PATH:/usr/somelocation/

Many thanks for you reply. You were right, curl wasn't installed! Running curl via it's full path and then amending my script has now resolved the problem. Thank you! :)
