Hello All, I have the following script and output. The man page says "Return a status of 0 or 1 depending on the evaluation of the conditional expression expression." Therefore, I thought that the two printf statements should print 1 and 0 respectively. But both of them print 0. I'm wondering what [[ should return if it is not used with a if statement.
$ cat main.sh #!/usr/bin/env bash printf '%d\n' `[[ 10 -gt 1 ]]` printf '%d\n' `[[ 1 -gt 10 ]]` if [[ 10 -gt 1 ]] then echo xxx fi $ ./main.sh 0 0 xxx -- Regards, Peng
