e.g. solaris:
/export/home/vbe $ ls -b | grep -v "/$" | xargs file -b
file: illegal option -- b
usage: file [-dh] [-M mfile] [-m mfile] [-f ffile] file ...
once -b removed works fine...

Not sure about the OS - this is a university box.
As for the shell it is a C shell.
So then, is there any workaround this situation? No other way to combine ls and file command to get a list of files?
I feel like I am really close but still not there .....
Maybe I am not clear enough - my task is to list the files from the current directory in the following format:
FileName FileSize FileType
So I was able to do the first 2 columns by using the following C shell:
Code:
awk 'BEGIN {printf "%-15s %-15s %-15s\n","Filename","Filesize","DateModified"}'
foreach file (*)
if (-f $file) then
set x = `ls -l $file`
#PRINT CURRENT DIRECTORY
#echo $x | awk '{ printf "%-15s %-15s %-3s %-3s %-6s\n", $9, $5, $6, $7, $8}'
echo $x | awk '{ printf "%-15s %-15s %-3s %-3s %-6s\n", $9, $5, $6, $7, $8}'
endif
end
Now I need to find a way to add the file type to that using filecommand
I tried your code:
Code:
ls -b | grep -v "/$" | xargs file -b
but that did not work.
If you change the %-6s\n in your awk printf command to just be %-6s and then add the following command:
Code:
file $file
after that echo | awk pipeline, you'll come close to getting what you want. But without file's -b option, you'll get the filename twice.
I don't like writing scripts using csh, but the following Korn shell script seems to do what I think you're trying to do:
<obscured>
and will work even if some of your filenames contain whitespace characters. I just added the file type output to the end of the output your script was producing. Obviously, it would be easy to change this to print the file type instead of the DateModified field your script produced if you don't want both fields in your output.
If this isn't what you want, please show us the output of the command:
Code:
uname -a
which will tell us what operating system and what version of that operating system you're using.

Thank you for your help - I really appreciate.
I am afraid that I have to use C Shell - part of the assignment.
Here is the output of the command:
Linux merlin 2.6.27.25-78.2.56.fc9.i686 #1 SMP Thu Jun 18 12:47:50 EDT 2009 i686 i686 i386 GNU/Linux
Give me one second and I'll try your suggestion.

I think that worked - all I have to do is to remove the extra notes after each file type i.e. PDF Document, version 1.0
I just need to keep PDF Document.
I think grep and sed may help.
