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 |

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 |
