rsh is removing double quotes

Question

rsh command is removing the double quotes in the remote shell.

For example: my command rsh 10.20.1.25 my_pgm -g "NAME1 NAME2" In remote shell my_pgm -g NAME1 NAME2

I want double quotes for -g option in remote shell too. Any idea?

Answer 1

To escape double quote inside a string use a backslash:

rsh 10.20.1.25 my_pgm -g "\"NAME1 NAME2\""

Actually, My C program is like this sprintf(cmd_string, "rsh 10.20.1.25 my_pgm -g \"NAME1 NAME2\"");

Ok, you mean using system(), see output on echo:

#include <stdlib.h>

int main(void)
{
    system("echo \"NAME1 NAME2\""); /* output: NAME1 NAME2 */
    system("echo '\"NAME1 NAME2\"'"); /* output: "NAME1 NAME2" */

    return 0;
}

Translated to yours (Note single quote and double quote around NAME1 NAME2):

sprintf(cmd_string, "rsh 10.20.1.25 my_pgm -g '\"NAME1 NAME2\"'");

Or as pointed out by @nos:

sprintf(cmd_string, "rsh 10.20.1.25 my_pgm -g \\\"NAME1 NAME2\\\"");
