execlp to sort
Hi, I have a very small program where I call execlp() to execute sort.

Everything works fine. But sort has a -T option which can be used to specify a temporary directory. Now when I use -T with execlp() it does not work.

Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/wait.h>
#include <fcntl.h>
#include <errno.h>

int main(int argc, char *argv[])
{
        int ret;

        ret = execlp("sort","sort","hugefile.txt","-T /u/mmr/somedir",NULL);
        if (ret == -1) {
                fprintf(stderr, "Could not sort file (%s)", strerror(errno));
                exit(1);
        }
        return(1);
}

sort when called using execlp() is unable to find the specified directory "somedir"

This is the error that I get.

Quote:
sort: cannot create temporary file: /u/mmr/somedir/sortPbxXPn: No such file or directory
However when I run the same command from the shell. Things work fine:

Quote:
%> sort hugefile.txt -T /u/mmr/somedir
does anybody have a clue on what might be going on? any input will be appreciated!

set_color

set_color(1)							       fish							      set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
