I am a new user to unix and stuck with a problem.
In ls -l command I want 3 columns to be displayed. They are Permissions, author and file name. I think I have to do ls -l and pipe the output to cut command.
Something like
ls -l | cut -d " " -f1,3,8
My problem is I dont know what should I give in delimiter in this case
Can anybody pls hep me regardsin this
Thanks
Prajakta

you can use tr to remove extra space and use single space as delimeter.
e.g.
$ ls -l | tr -s " "| cut -f1,3,8 -d" "
hope this helps

Answer:

ls -l | sed 's/ */ /g' | cut -d" " -f1,3,9
The problem is there are multiple spaces between some of the fields. To fix it, pipe the results into the sed command to convert any two or more spaces into one.
It doesn't show very well on the screen, but there are two spaces between the "'s/" and the "*/", and there is one space between the "*/" and the "/g'" .
And the file name is in field 9, not 8.

Use awk, if you already know which columns to diplay.
ls -l pattern | awk '{print $1 $2 $3}'
to print cols 1,2,3. awk uses the space(s) as default delimiter.

Hi,
Suppose your files are delimeted by |
like
|abc|cdb|hh557788|red|green|
Then you give "|" as delimeter and f4 if you want to pick up fourth delemited word.
