BASH Function to Check if sudo Available

in blurt •  6 days ago 

sudo is the command to allow normal users perform some escalated operations. We can use the following BASH function to check to see if the sudo command is available. This is done via the which command which searches the command in the $PATH path.

# 0 - ok
# 1 - nok
    local result=1
    which sudo 2>&1 1>/dev/null
    [ $? -eq 0 ] && result=0
    return $result

This function works in BASH script on Linux platforms and also the Windows Subsystem for Linux or Cygwin.
