Hidden files

[Ngoh Chean Siung]

Hi,

1) All the hidden files is start with .abc
Am I right?

2) How to make a file become hidden?

3) If login as root, all the hidden files can be viewed normally. But for normal user, they have to user ll -a command to view hidden files. Is there any command to enable the particular user to view the hidden files without -a command? (The user id for the user must not same as root which is 0)

regards.

1. Yes
2. The file need to begin with dot.
3. Use alias ls="ls -al" in .shrc or .cshrc.

1) yes

2) rename it to have a "." in front of it.

3) No, sorry

Hi Sanjay,

1) What is .cshrc and .shrc used for?

2) I need to put in "ls -al" inside .cshrc
Where should I put it? Attach is my .cshrc file.

regards.

[Sanjay Kumar Suri · Accepted solution]

.shrc & .cshrc are optional shell startup scripts.

POSIX users define it using ~/.shrc whereas C Shell users use ~/.cshrc.

Use vi .shrc to define as below:

alias ls="ls -al"

Hi,

it depends on which shell is configured for you! It is fixed in the passwd file.

Also you can change it 'csh' for c-shell, for example.
.cshrc is read when logging in with csh,
.profile is read with ksh (korn-shell).

Write for example:
alias ll 'ls -al'
anywhere in your .cshrc

Since you are using csh use the syntaz as listed in the sample .cshrc file

# alias d dirs
# alias pd pushd
# alias pd2 pushd +2
# alias po popd
# alias m more

THere are some files which are user initialization files

for sh/ksh .profile
csh .cshrc and .login

Just inside your .cshrc,

alias ls ls -cFa

Once you put this inside the .cshrc file it becomes persistent everytime you log in.
to be simple the file is used to create the customized user enviroment.

Hidden files start with dot "."

Hi,

Is there any difference between

alias ls ls -cFa & alias ll ls al

regards.

[Mark Grant]

"ll" is just a hard link to "ls" with the command doing different things depending on the name is was called as.

With this in mind, there is no difference between alias "ll" and alias "ls"

[Ngoh Chean Siung]

Hi,

Actually the one that I not clear is

-cFa & al

What is -cFa & al stand for?

Any different?

regards.

Hi,

you can check this with 'man ls'

Option F shows a slash if it is a dir, an * if the file is executable, a @ if it is a symbolic link.
-c shows last modification of inode
