Hi, I wrote a shell script to check if string entered is null. The test -n option is not giving correct answer. It works fine with -z option.
echo "enter a string" read a # test -n STRING # the length of STRING is nonzero if test -n $a; then echo "non zero" else echo "zero" fi # test -z STRING # the length of STRING is zero if test -z $a; then echo "zero" else echo "non zero" fi Pls tell me why is it so? -- Pushparaj Shetty D.
