To run an ec-perl standalone script from cygwin, these lines have to be added to your script
#!/bin/sh
exec "c:/Program Files/Electric Cloud/ElectricCommander/bin/ec-perl" -x "`cygpath -m "$0"`" "${@}"
#!perl
#Rest of script…
Key Legend:
-
The 'exec' shell command says, "Replace this sh process with the execution of the following command, rather than spawning it as a child." This keeps the shell from running the rest of the script in its context after ec-perl completes.
-
-x says that when Perl runs, it should ignore everything before the #!perl line.
-
CloudBees CD (CloudBees Flow)'s perl is a win32 perl, so it won’t take unix-y paths for the script to run. Thus, we use "cygpath --m" to convert to Windows-style, '/' delimited (e.g. --m means "mixed" format).
-
$0 is the name of the script, as run on the shell (e.g. /tmp/ec.pl, ./ec.pl, ec.pl (for path lookup)).
-
"${@}" means all of the args from the command-line should be passed from this shell script (remember, this is an sh script to start with) to the program we’re 'exec’ing.
