Alternatives of chmod +x Command
Other than using chmod +x, alternative approaches include using octal notation, such as chmod 755, or the symbolic notation, like chmod u+x. Each method offers flexibility in setting permissions based on the user, group, and others.
# Grant execute permission to the owner
$ chmod u+x filename

chmod [options] permissions file(s)
Operations
In Linux and Unix, operations that should work in the chmod command are given below:
- -R: Recursively change permissions for directories and their contents.
- +: Add permissions.
- -: Remove permissions.
- =: Set permissions explicitly.
File Level permissions-
Permissions are represented using a three-digit octal (base-8) number. Each digit corresponds to a permission set (owner, group, others) and is the sum of the values:
- 4: Read (r) Grants read permission
- 2: Write (w) Grant write permission
- 1: Execute (x) Grant execute permission
Usage of `chmod +x <filename>` in Linux
The command chmod +x <filename> is used to add executable permissions to a file in Linux system. following these steps-
chmod: This is the command used to change file permissions.
+x: The +x option specifies that executable permissions should be added. The + indicates addition, and x represents the executable permission.
<filename>: Replace this with the name of the file for which you want to add executable permissions.
chmod +x myfile.sh
So, here the command grants execute permissions to the file named myfile.sh. After running this command, the file becomes executable, allowing users to run it as a script or program.
Stepwise Implementation
So, here we perform chmod +x <filename> command which is used to add executable permissions to a file in a Linux system the step-by-step command to perform:
Step 1: Firstly open the terminal by searching for it in your application menu or using a keyboard shortcut like Ctrl + Alt + T.
Step 2: Navigate to the Directory and use the cd command where your file is located.
cd /path/to/your/directory
Step 3: Execute the chmod Command, Run the chmod +x command followed by the name of the file for which you want to add executable permissions.
chmod +x temp.sh
Step 4: Now we can verify the changes by listing the files in the directory using the ls command.
ls -l
Once you enter the above command you will see the output as following:
Step 5 : Also we can Execute the chmod Command with Numerical Values.
chmod 755 temp.sh
