of CHMOD's and what they mean.
1: General Info.
When using a UNIX system it is sometimes necessary to change file permissions.
This is done using the CHMOD command. There are two different ways to chmod
a file.
Certain FTP clients such as Cute FTP and WS/FTP Pro allow for
a chmoding directly within FTP. To do this you would highlight the file that
you want to use, and select from the command menu "change file permissions."
There is on option for "manual." This is where you will enter the
desired CHMOD. Many other FTP clients will support CHMODing as well, we recommend
checking the documentation.
2: Reasons
for CHMODING
CHMODing files can be done for a variety of reasons. You can CHMOD files to
do things such as: mark them executable, give them write permission, restrict
access to them, and a variety of other reasons. It is important to note that
chmoding is nearly impossible to avoid. If you are trying to run a certain cgi
script it could require execute permissions on the script itself, write permissions
on a directory, and read on an informational page. Your cgi scripts should contain
the proper documentation to inform you of the proper CHMOD's.
3: List
of CHMOD's and what they mean.
chmod 777 filename The file is available for Read, Write, and Execute for the
owner, group, and world.
chmod 755 filename The file is available for Read, Write, and Execute for the
owner; and Read and Execute only for the group and world.
chmod 644 filename
The file is available for Read and Write for the owner, and Read only for the
group and world.
chmod 666 filename The file is available for Read and Write for the owner, group,
and world. I wonder if the 666 number is just a coincidence. Anybody can create
havoc with your files with this wide-open permission mask.
