Shell Script Passing Parameters For Directory Listing
i have this basic piece of code that i am trying to debug to accept input parameter to be able to display a directory listing of files.

Code:
cd /u02/app/eatv/dev/out
CURDIR=`pwd`
echo directory listing of $CURDIR
echo
if [ $1 -e 0 ]; then
  ls -latr
else
  ls -latr $1
fi

basically if the script does not see any parameter being passed it will display all the file listing of the current directory. and if it find a parameter it display only a specfic files on the directory. the above code does not work and when i run i am getting this error:

Code:
$ sh dir_list_eatv_out.sh *.ini
directory listing of /u02/app/eatv/dev/out

dir_list_eatv_out.sh[20]: -e: 0403-012 A test command parameter is not valid.
ls: 0653-341 The file cca_monthly_load_data.ini does not exist.
$

thanks,
warren

Try
Code:
if [ $1 -eq 0 ]; then

Or
Code:
if [ $1 = "0" ]; then

regards,
Arun.

not sure what you're after, but....
Code:
if [ ${#} -eq 0 ]

thanks. in pseudo code

if input file variable is null then
display the file variable listing
else
dislay all the files in the directory
end if

assuming the i pass a parameter of *.ini it will display all the files having an extension of *.ini otherwise displays all the files on the directory

i tried and still there is an error
Code:
#!/bin/sh
cd /u02/app/eatv/dev/out
CURDIR=`pwd`
echo directory listing of $CURDIR
echo
if [ ${1} -eq 0 ]; then
  ls -latr
else
  ls -latr $1
fi

Code:
$ sh sample.sh *.ini
directory listing of /u02/app/eatv/dev/out

sample.sh[6]: cca_monthly_load_data.ini: 0403-009 The specified number is not va
lid for this command.
ls: 0653-341 The file cca_monthly_load_data.ini does not exist.
$

Check for an empty parameter:
Code:
cd /u02/app/eatv/dev/out
CURDIR=`pwd`
echo directory listing of $CURDIR
echo
if [ -z "$1" ]; then
  ls -latr
else
  ls -latr $1
fi
