making a script in /usr/local/bin shareable

[RFahy]

Boogy took the lead. SUID/SGUID bits was what I would've suggested as well.

[vickey_20]

can you give me an example using a sciptname how to set it

What is a chmod command?

Chmod command sets UNIX file permissions. First you need to telnet or SSH to the target computer, then in the command prompt you need to execute a chmod command. Also you can set the permissions with the help of other programs, such as FTP client.

2. Syntax and examples of the shell chmod command (telnet or SSH)

Syntax of the chmod command is the following:

prompt> chmod [options] permissions file[s]

The word "chmod" should be entered all in lowercase letters. Options can be:

* -R, set permissions recursively
* -f, "forced" or silent mode
* -v, "verbose", show information for every file processed
* -c, show information only if changes are made to the file

Permissions could be one of the following:

* Octal numeric format, with a leading zero like "0644"
* Octal numeric format, without a leading zero like "644"
* Text form like "a+r", "u=rwx" or "o-w", you can use several comma separated text form permissions

File[s] can be either

* relative path to the file like "file.pl"
* absolute path to the file like "/var/spool/mail/paul"
* several space separated files like "file.pl /var/spool/mail/paul"
* file name mask like "*.html" or "*"

What text permissions values mean:

u Sets permissions for the owner of the file, e.g.: "u+w" allows the owner to write to the file
g Sets permissions for the group (to which owner belongs), e.g. "g-x" suppresses the execution of the file by the group
o Sets permissions for other users (that are not in group), e.g.: "o=r" allows others only to read the file
a Sets permissions for all (owner, group and others), e.g.: "a-w" disables write access to the file for everyone
= Assigns the permissions, e.g. "a=rw", sets read and write permissions and disables execution for all
- Removes certain thing[s] from the permissions, keeping all other (not involved) permissions. E.g. "a-x" disables execution of the file for everyone, this example doesn't touch read and write permissions.
+ Adds certain thing[s] to the permissions, keeping all other (not involved) permissions. E.g. "a+x" allows execution of the file for everyone, this example doesn't touch read and write permissions.
r Sets read permissions
w Sets write permissions
x Sets execute permissions
t Sets sticky bit, e.g. "o+t" sets sticky bit for a file
s Sets SUID or SGID. E.g.: "u+s" sets SUID, "g+s" sets SGID.

2.1. Examples

Here are the examples of the chmod command. All commands do the same thing, except that the first four set SUID & SGID and sticky bits to zero and the last two don't touch SUID & SGID and sticky bits:

prompt> chmod 0755 script.sh
prompt> chmod 755 script.sh
prompt> chmod u=rwx,g=rx,o=rx script.sh
prompt> chmod u=rwx,go=rx script.sh
prompt> chmod u+rwx,g+rx,g-w,o+rx,o-w script.sh
prompt> chmod u+rwx,go+rx,go-w script.sh

This example performs recursive chmod for the directory:

prompt> chmod -R 755 mydirectory
