I encounter a problem when launching a script using sudo, though I have no problem and the script works fine without sudo.
The Line is :
mapfile -t dataList< <( tac /tmp/result.log | grep 'Command' | cut -d" " -f1 )
The error is "Syntax error near the unexpected symbol " < ".
The sudo command is :
sudo -u victor /tmp/parse.sh
Thank you all for help...
Sounds like a different shell is executing your script, one which doesn't understand the used syntax.
Your script /tmp/parse.sh might lack the #!/bin/bash (or similar) in its head line, and a different shell (root's login shell?) might be used to execute it.
This could be fixed by adding the missing #! line in the script header (recommended), or by calling the shell explicitly:
sudo -u victor bash /tmp/parse.sh
