Name: Shell command for
Linux file management
·
Make a directory and then make a text file to do operations.
· Run “ls -l” to see the permissions that the text file have.
·
Here,
r- reading permission which value is 4.
w- writing permission which value is 2.
x- executing permission which value is 1.
So, if we want to give full permission to the file we have to input
“777”.
Use “chmod 777 file name” to give the permission.
·
In “rwxrwxrwx” first rwx in for the user middle rwx is for
the group and last rwx is for the others part.
We
can also give and take permissions from these part in different way like,
If
we want to take execution permission from all of the parts we can apply “u-x”,
“g-x”, “o-x”.
·
We can also see umask of any file just running “umask”.
