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.
1 2 3 4 5 6 7 8 9 | # 0 - ok # 1 - nok is_sudo_available() { local result=1 which sudo 2>&1 1>/dev/null [ $? -eq 0 ] && result=0 return $result } |
# 0 - ok
# 1 - nok
is_sudo_available()
{
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.
