Shell Script For Getting List Of File name In A directory

[kayanaat sidiqui]

Hi,

Can any body please tell me the how to write Shell Script For Getting List Of File name In A directory;

Same In DOS also.

Thanks,
Kaya.

Maybe I am missing something here, but couldn't you just do:

ls /some/directory

and in DOS:

dir c:/some/directory

Why do you need a script?

[Pat Farrell]

you might need to do

ls -a /some/directory

to get the hidden files.

kayanaat,

try this . dint check it myself..

#!/bin/sh
for i in `ls -a *.*`
do
echo "$i"
done

Doing an ls under any directory will give you the list of all files(use -a to get the hidden files details), but the output will include all the details of the files like "permission", "owner of the file", "time stamp" etc....so if you want the name of the files to be displayed ONLY(may be you like to pass the file names as parameter to some function or script), try this:

ls -a <directory> | awk {'print $9'}

Note: The numeric value 9 denotes the column number which denotes the file name.

but the output will include all the details of the files like "permission", "owner of the file", "time stamp" etc....

Thats false, unless specifies -l option.

what is the benefit, compared to

#!/bin/sh
for i in *
do
echo "$i"
done

or even

ls -a 

btw - *.* will mask dotfiles.

what is the benefit

ls -a would just display files... whereas the script is more flexible and inside loop can do any operations with filenames.. requirements dont stop there..would you write a script to just display files or make it compatible to changes that come in future..

which mets the requirements

no, you have to fix it by hand. If we like to delete the files, you will replace your echo with an rm, and I will replace ls -a with rm.

Which changes that come in future? I don't see what script can do, which I can't do with ls -a - planning for an unforeseable future needs far more information than given in this post.

rm is just simple operation. What if some consecutive operations , use of | would not be efficient in such cases.

@Balu Sadhasivam:

You 're right . If the description of the problem isn't appropriate, the solution of the problem I postet isn't appropriate. Absolutely right.

[Balu Sadhasivam]

Steve , Both were right .. its just matter of other parameters.
