This brings up the window shown below.On the popup menu that is displayed, select the "File Attributes.Once the file is there, right-click the file.For instance, this chmod capability is supported with FileZilla, and I'll briefly describe how this works with FileZilla:
If you don't have ssh or telnet access to your server, you can often perform this same chmod command functionality using your FTP client. This next chmod command is pretty wide open, and can be read as, "Make this file readable, writeable, and executable everyone": chmod 777 runme.cgi The following Linux chmod command says, "Make this file readable, writeable, and executable by the owner and the owner's group and make it readable and executable by all others": chmod 775 runme.cgi There are other ways of issuing the Linux chmod command, and I'll show you a few ways here that are roughly equivalent to the chmod +x command shown above.īefore I show these other options, it's good to know that the +x option shown above says, "Whatever the file permission is, add the execute bit to it, for the owner, the owner's group, and all others." (That's what we did in the chmod example above.) The options are set in two file mode bits: Set-user-ID (SISUID) with. I'm not going to get into all the details here, other than to say that if you see those x's in the first ten columns of your listing, your Perl script now has the execute permission it needs. To give owner, group and everyone else permission to execute file: chmod +x /path/to/file chmod 755: Only owner can write, read and execute for everyon A superuser or the file owner can use a chmod command or chmod() function to change two options for an executable file. rw xr- xr- x 1 myusername mygroup 1,000 May 19 18:07 runme.cgi If you have ssh or telnet access to your server, just log in to your server, move to the directory where your file is located (using the cd command), and then run the Unix/Linux chmod command.įor instance, let's say you have a Perl script named runme.cgi, and it's located in a directory named /web/sites/First, move to that directory with the cd command, like this: cd /web/sites/Then make the Perl script executable by running this chmod command: chmod +x runme.cgiĪfter running this chmod command, if you'll then run the ls command on that file, you should see it has execute permissions, like this: ls -l runme.cgi
#Unix make file executable chmod how to

Linux chmod FAQ: Can you share an example of how to make a shell script executable with the Unix/Linux chmod command?Ī lot of times in the web world you're given a Perl script by someone, and they say, "Put this script on your server, make it executable, and yada yada yada."
