How to use -c option in useradd

[sean04]

when using the command useradd to create a new user, I want to be able to add to the comment field with the -c option so my question is which is the correct way to add a user by the name of T1:

1. useradd -c This is my comment T1

2. useradd -c "This is my comment" T1

3. useradd -c 'This is my comment' T1

4. MyComment = "This is my comment"
useradd -c MyComment Tester

Hi,

2 and 3 will work. For 4 you need to use something like:

# mycomment="this is my comment"
# useradd -c "$mycomment" T1
# finger T1
Login: T1                               Name: this is my comment
Directory: /home/T1                     Shell: /bin/sh
