[Help/Solved] Conditional Operations for Shell Scripting
 
okay guys i would really appreciate it if someone tells me how can i produce a command that goes as follow

Code:
echo $x

if [ 80 > $x > 20 ];then

Command

fi
ive tried this

Code:
if [ 80 -gt $x -gt 20 ]
and it failed to work

also tried


Code:
if [ $x -ge 20 ];
elif [ $x -le 80 ];then
same thing , didn't work


i would really appreciate some help as i know its simple to you but not me cause so far I've been stuck , as I'm working on this shell script and need to put the X between two values.

cheers,
bakuur

It should be
Code:
if [ $x -gt 20 ] && [ $x -lt 80 ]; then
    command
fi
