This page contains instructions on how to change the permissions of your files via a common SSH client – Putty.<\/span><\/span><\/p>\n

Why would you want to change file permissions?<\/h3>\n

Permissions are needed to protect files, and to tell the server how to handle these files. If a file does not have the correct permissions, your script may not run, or anyone may be able to access your files and make unwanted changes.<\/span><\/span><\/p>\n

Changing the permissions<\/h3>\n

To change the permissions of a file in SSH, once you have logged in you can use the CHMOD command. Some common examples of CHMOD:<\/span><\/span><\/p>\n

chmod number filename <\/span><\/span><\/p>\n

chmod 600 example.html - This will give the file read and write permissions by the owner only (-rw-------).\nchmod 644 example.html - This will give the file read and write permissions by the owner and read by everyone else (-rw-r--r--).\nchmod 700 example.html - This will give the file read, write and execute permissions by the owner only (-rwx------).\nchmod 755 example.html - This will give the file read, write and execute permissions by the owner, read and execute permissions by the group and others (-rwxr-xr-x)\nchmod 666 example.html - This will give the file read and write permissions by everyone(-rw-rw-rw-) (NOT RECOMMENDED)\nchmod 777 example.html - This will give the file read, write and execute permissions by everyone (-rwxrwxrwx) (NOT RECOMMENDED)<\/pre>\n
Changing the ownership<\/h3>\n
To change the ownership of a file in SSH, you can use the CHOWN command. e.g:<\/span><\/span><\/p>\n
chown owner filename<\/span><\/span><\/p>\n
chown user example.html<\/pre>\n
This will change the owner of the file to be whoever you specify in the command. You can change the owner of a file if you are the root user, or the owner of the file.<\/span><\/span><\/p>\n
