I’m trying to execute a shell command via a perl script that looks as follows
$cmd = 'cat <(ssh -o \"StrictHostKeyChecking no\" dev-adm1 \'sudo cat /etc/httpd/conf/httpd.conf\')';
exec $cmd;
This is throwing an error
sh: -c: line 0: syntax error near unexpected token `('
sh: -c: line 0: `cat <(ssh -o \"StrictHostKeyChecking no\" dev-adm1 'sudo cat /etc/httpd/conf/httpd.conf')'
The command works directly on the shell but not like this. What am i missing?
which shell did you use to test this command?
my first guess is that you used bash or ksh, while sh (used by perl exec) doesn’t know the ‘(‘ syntax
