You are writing shell script and got too many arguments error

While writing bash script, if you got this error, check where you are making expression test like in

if [ $somevar = "value"]; then
..

if the $somevar is something you are getting it from another command [ say grep or ls] which happen to return a lot of results that are separated by space or something you end up having it being

if [file1 file 2 file 3 = "value"]; then
…

The easiest solution for this is to enclose the variable in double quote like

if [ -n  "$somevar"]; then
some more commands goes here
