bash - How to display column headers in 'ls -l' command in unix/linux? -

-

i want display column headers when type ls -l command in bash shell in unix/linux

when type ls -ltr on command prompt following.

-r--r--r--  2   makerpm   root   1898   jan 28 14:52   sample3 -r--r--r--  2   makerpm   root   1898   jan 28 14:52   sample1

what want know whether ls' has options display column headers:

file_permissions  owner group   size   modified_time  name -r--r--r--  2  makerpm   root   1898   jan 28 14:52   sample3 -r--r--r--  2  makerpm   root   1898   jan 28 14:52   sample1

no, there's no such option in ls.

you can add like:

alias ll="ls -l | sed '1ifile_permissions owner group size modified_time name'"

then ll show result of ls -l header. doesn't because it's not aligned on columns ...
