How to use sudoers and regular expressions with grep

I am trying to do grep on all log files which are under directory /var/log/application/archived/

And I have sudo access. Trying like below is giving me error

sudo grep 'checkThis' /var/log/application/archived/*.log

Error

grep: /var/log/application/archived/*.log: No such file or directory

I tried with escape char but doesn't seems to work

and If I give any one file name instead of * it gives me result.

Eg : sudo grep 'checkThis' /var/log/application/archived/firstLogFile.log this gives me expected response

Solution

  • Use below command to do grep of all log files with sudo access

    sudo sh -c "grep 'stringToSearch' /var/log/archived/*.log"
