ls -t *.* > temp/files.txt
ls -pt */ >temp/dir.txt
and after somehow connect the two .txt's to be in columns ....
but i don't find a ls command to appear only the directories...
ls -pt */ gives me also the contents of the directories.
Any ideas??

Hi group,
Can you please tell how to delete specific columns from a file.

awk -F, '{ print $1" "$2" "15 }' input.txt > output.txt will delete all other columns. But this is in a way to copy some particular columns.
But is there any other way to select just some... (11 Replies)

man
MAN(1) General Commands Manual MAN(1)NAME
man - print sections of this manual
SYNOPSIS
man [ option ... ] [ chapter ] title ...
DESCRIPTION
Man locates and prints the section of this manual named title in the specified chapter. (In this context, the word `page' is often used as
a synonym for `section'.) The title is entered in lower case. The chapter number does not need a letter suffix. If no chapter is speci-
fied, the whole manual is searched for title and all occurrences of it are printed.
Options and their meanings are:
-t Phototypeset the section using troff(1).
-n Print the section on the standard output using nroff(1).
-k Display the output on a Tektronix 4014 terminal using troff(1) and tc(1).
-e Appended or prefixed to any of the above causes the manual section to be preprocessed by neqn or eqn(1); -e alone means -te.
-w Print the path names of the manual sections, but do not print the sections themselves.
(default)
Copy an already formatted manual section to the terminal, or, if none is available, act as -n. It may be necessary to use a filter
to adapt the output to the particular terminal's characteristics.
Further options, e.g. to specify the kind of terminal you have, are passed on to troff(1) or nroff. Options and chapter may be changed
before each title.
For example:
man man
would reproduce this section, as well as any other sections named man that may exist in other chapters of the manual, e.g. man(7).
FILES
/usr/man/man?/*
/usr/man/cat?/*
SEE ALSO nroff(1), eqn(1), tc(1), man(7)BUGS
The manual is supposed to be reproducible either on a phototypesetter or on a terminal. However, on a terminal some information is neces-
sarily lost.
