Check variable contents 1

[tempest92]

hi,

can someone please tell me how i would test if a variable contains a space (this is information put in by users via a menu option).

the variable should be v1="a1,a2,a3,a4,a5" but i need to check that it is not v1="a1, a2,a3,a4,a5" for example.

Thanks in advance !!

check the returncode of
echo "$v1" | grep -q "

Why not let your program handle it a bit user-friendly: just squeeze the whitespace out after the user has entered the value...

something like:

...
read answer
answer=$(echo "${answer}"|tr -d '[ \t]')
...


HTH,
