From: Alex Vinokur on 26 Nov 2005 02:43 I tried to execute the following command line: strcpy (cmd, "ls"); strcpy (args[0], "ls"); strcpy (args[1], "-l"); strcpy (args[2], "*.c"); args[3] = NULL; execvp (cmd, args); However I have got an error message: ---------------------------- ls: '*.c': No such file or directory ---------------------------- How to pass arguments with '*' to execvp()?

The shell is responsible for expanding pathnames containing * . So run a shell that runs ls -l *.c as in e.g. sh -c ls -l *.c

Using opendir, readdir and fnmatch. You can also have a look at the sources of bash. -- __Pascal Bourguignon__ http://www.informatimago.com/

[snip] OK. I found sample at http://docs.hp.com/en/B2355-90694/fnmatch.3C.html ----------------------- pattern = "*.c"; while(dp = readdir(dirp)){ if((fnmatch(pattern, dp->d_name,0)) == 0){ /* do processing for match */ ... } } ----------------------- But how to apply that to passing args to execvp (cmd, args) ? -- Alex Vinokur email: alex DOT vinokur AT gmail DOT com http://mathforum.org/library/view/10978.html http://sourceforge.net/users/alexvn

You implement the "do processing for match" part. -- __Pascal Bourguignon__ http://www.informatimago.com/ There is no worse tyranny than to force a man to pay for what he does not want merely because you think it would be good for him. -- Robert Heinlein |
