Hello, I am getting Expression syntax message and I cannot figure out what's wrong. This program will print all the odd numbers between 0 and the one the user enters, in cshell. I think my logic is either good or almost there, but i dont see the errors. I think it could be the spaces between... (1 Reply)
Hi
what's the correct way of writing if
1)if "$time_diff" -gt 5

echo "killing hung process \n"
fi
2)if test $time_diff -gt 5
then
echo "killing hung process \n"
fi
where -time_diff=$(($Sam - $current_min))
and current_min=`date +%M`
infact both are giving Syntax... (1 Reply)

Hello,
I am relatively new to UNIX scripting and am learning a lot. I have already tried several searches on this website and have tried various syntax options suggested to no avail. I am obviously not writing the script correctly. I really do appreciate any and all the help.

I'm pretty new to shell scripting, but I am catching on quick. I did see one of the stickied threads about the csh, and I think this is relevant, but I don't understand enough to make a decision based on it. So as you'll see below, I use the |csh pipe, and if that is not correct, I'm certainly... (2 Replies)

gfs_chmod
GFS_CHMOD(3)GFS_CHMOD(3)NAME
gfs_chmod - change permissions of a file
SYNOPSIS
#include <gfarm/gfarm.h>
char *gfs_chmod (char * gfarm_url, mode_t mode);
DESCRIPTION
gfs_chmod() changes the mode of the file given by gfarm_url. Permission bit masks of mode are similar to ones of mode parameter to
chmod(2), though only the least 9 bit are effective.
An executable file cannot be changed to a non-executable file and vice versa, unless the number of fragment of the file is only one. In
detail, a file has multiple fragments with any execution bit should not be changed to that with no execution bit. It is necessary to have
at least one execution bit. Similarly, a file has multiple fragments with no execution bit should not be changed to that with any execu-
tion bit.
RETURN VALUES
NULL The function terminated successfully.
GFARM_ERR_NO_MEMORY
Insufficient memory was available.
GFARM_ERR_AUTHENTICATION
User authentication failed when connecting to gfmd(8) or gfsd(8).
GFARM_ERR_PERMISSION_DENIED
The parent directory of gfarm_url did not allow write permission.
GFARM_ERR_OPERATION_NOT_PERMITTED
The effective UID does not match the owner of the file, and is not zero. Or an attempt was made to change an executable file with
more than one fragment to a non-executable file, or vice versa.
GFARM_ERR_NO_SUCH_OBJECT
The file does not exist.
GFARM_ERR_NOT_A_DIRECTORY
A component of the path prefix is not a directory.
Others An error except the above occurred. The reason is shown by its pointed strings.
