I need to inspect the output from en external program (run via the
${run} expansion). The program outputs multiple lines, only the first
is relevant to me. What is the least painful way to extract it? I mean
the least number of backslashes and curlies.In the past when I thought I needed this, it turned out the program had a daemon mode replying on a socket, so I could use the readsocket expansion which has a built-in separator option. Unfortunately, there is no daemon mode now, and the run expansion has no such option (hint hint feature request :) -- Ian -- ## subscription configuration (requires account): ## https://lists.exim.org/mailman3/postorius/lists/exim-users.lists.exim.org/ ## unsubscribe (doesn't require an account): ## [email protected] ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
