Check for empty string
Hello All,
I have written shell script whcih at the max 3 parameters. When only one commandline argument and other two command line arguments are passed as empty string like eg : archive ' ' ' ' Then i need to check whether the commandline arguments are empty or not. i have use -n and ! -z but both of them fail for the above scenario. Please let me know what is the alternative to solve this problem. Thanks in anticipation |
