~$ cat ~/forked_sh.sh
#/bin/sh
echo THis_is_return
sleep 2;


~$ socket=wlan0
~$ echo $socket
wlan0
~$ mystring_$socket=.`/forked_sh.sh`
mystring_wlan0=THis_is_return: command not found

I was expecting that it will assign, but the bash running as whole as 1 string in place of $ a=sfkjsdf

    are your first backtick and the '.' reversed? – user208145 Apr 01 '17 at 21:46

    As noted by @user208145, you have a typo. you need mystring_$socket='./forked_sh.sh' (with backticks). Or better: mystring_$socket=$(./forked_sh.sh) – Stephen Rauch Apr 01 '17 at 21:55

    eval is almost always the wrong answer -- there are too many ways for it to go wrong. In this case, declare would work, and be much safer. – Gordon Davisson Apr 02 '17 at 00:56
