[: too many arguments error in bash script

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
