variable numerical test
Hi I have a variable which should be any number between 1 and 50. It could also be any string/empty string. I have a code written below. The point is when the variable contains string. I don't want the code below to error out. Instead fall in the else bucket. Code:
[ $var -lt 1 -o $var -gt 50 ] && dothis_1 || dothis_2 |
