How to Get the File Input from Parameter
Code:
pdir=`pwd`
if [ $# -lt 1 ]; then
 echo current directory $pdir
 ls -altr
 echo
fi
for f in $*
do
    # directory
    if [ -d $f ]; then
      echo current directory $f
      cd $f
      ls -latr
      echo
    fi

    # but you can test file/dir
    # regular file only
    if [ -f $f ]; then
      echo current directory $pdir
      ls -altr $f
      echo
    fi

done

i have a basic code on shell script that accepts parameter for directory name with or without a filename or extension file name.

if i enter this below on the command line
Code:
sh dir_file_list.sh /u02/app/eatv/dev/out/*.txt

it give me this output:
Code:
current directory /export/home/ccalftdv/apps
-rw-r--r--    1 ccalftdv ccalogrp          7 Jun 30 09:30 /u02/app/eatv/dev/out/
sample.txt

$

how do i capture the string *.txt or the filename on the input parameter? thanks.

If i have got your question right, to capture the filename, use the 'basename' command.

#basename /u02/app/eatv/dev/out/sample.txt
sample.txt

Code:
#!/bin/sh
pdir=`pwd`
if [ $# -lt 1 ]; then
 echo current directory $pdir
 ls -altr
 echo
fi
for f in $*
do
    # directory
    if [ -d $f ]; then
      echo current directory $f
      cd $f
      ls -latr
      echo
    fi

    # but you can test file/dir
    # regular file only
    if [ -f $f ]; then
      pfile=`basename $f`
      echo current directory $pdir
      ls -altr $pfile
      echo
    fi

done

thanks. i added the basename command and i was getting this error:
Code:
$ sh dir_file_list.sh /u02/app/eatv/dev/out/*.txt
current directory /export/home/ccalftdv/apps
ls: 0653-341 The file sample.txt does not exist.

Before you have the line "ls -altr $f", you need to run the 'cd' command to go to the current directory pdir.

Code:
#!/bin/sh
pdir=`pwd`
if [ $# -lt 1 ]; then
 echo current directory $pdir
 ls -altr
 echo
fi
for f in $*
do
    # directory
    if [ -d $f ]; then
      echo current directory $f
      cd $f
      ls -latr
      echo
    fi

    # but you can test file/dir
    # regular file only
    if [ -f $f ]; then
      pfile=`basename $f`
      pdir=`dirname $f`
      echo current directory $pdir
      cd $pdir
      ls -altr $pfile
      echo
    fi

done

thanks that works when i added the change directory cd command. lastly is to fix the display. when i run it gives me this directory listing where the display for the current directory was repeated.

Code:
$ sh dir_file_list.sh /u02/app/eatv/dev/out/*.txt
current directory /u02/app/eatv/dev/out
-rw-r--r--    1 ccalftdv ccalogrp          7 Jun 30 09:30 sample.txt

current directory /u02/app/eatv/dev/out
-rw-r--r--    1 ccalftdv ccalogrp          7 Jun 30 17:05 sample2.txt

current directory /u02/app/eatv/dev/out
-rw-r--r--    1 ccalftdv ccalogrp          7 Jun 30 17:05 sample3.txt

$

it should look like this:
Code:
current directory /u02/app/eatv/dev/out
-rw-r--r--    1 ccalftdv ccalogrp          7 Jun 30 09:30 sample.txt
-rw-r--r--    1 ccalftdv ccalogrp          7 Jun 30 17:05 sample2.txt
-rw-r--r--    1 ccalftdv ccalogrp          7 Jun 30 17:05 sample3.txt

      cd $pdir
      ls -altr $pfile
    fi

done

i modified the script a bit and i was able to get the expected results.
