in thread Capture output from backtick commands using sudo

Hi, I stumbled across the same issue as you. In fact, since sudo will return: 'Upon successful execution of a program, the exit status from sudo will simply be the exit status of the program that was executed.' - you will not the the result of the 'ls'. In a specific case, what I wished for was the output of the executed program ('ls', for you). Did you find an answer for this? I'd really prefer not to use any temp files. Thanks! Norbert

    Huh? Give perl -E 'say `sudo "/bin/ls"`' a try. The exit status is not the STDOUT of the programme, but it's "return code". Like: did the command succeed?
