I try to write a C program which lists the output of a paticular command with all the available options (a to z) for the command in the directory of execution.
This program will generate the output if the option exists for the particular command else it will display some message saying "Option not available for the command".
ex: ls command has option "l" but not a option "y".
It will display the output on ls -l execution and error message on ls -y execution.
I am passing the "command to be executed(ex:ls,more)" in the command line argument. With in the program, I am using a while loop which initiated with 'a' and runs up to 'z'. I am using the "system()" unix call for the execution of command. please find my program below:
on compiling the program with cc, its giving a warning message "multi-line string literals are deprecated"
But however on execution of the program, the output is as follows:
Please help me in this..
Thanks,
Ramkrix.
