Question

In Linux, there are always more than one ways of performing a task.

For example, to list all directories under /etc/ folder, you can issue:

$ls -ld /etc/*/

$find /etc/ -maxdepth 1 -type d

$ls -l | grep ^d

…

Can you come up with two ways of displaying only regular files under /etc/ folder ?

Answer 1

  

Displaying only regular files under /etc folder

1.Find command can be used to display regular files.

syntax: find /path option filename

find /etc/ -maxdepth 1 -type f -ls

>f is used for regular files.

>maxdepth 1 is used to stop the find command descending into subdirectories.

2.List command can be used to display regular files.

ls -l /etc/ | grep "^-"

> -l indicates regular file.

> grep command will return the lines starting with hyphen.
