UNIX for Dummies Questions & Answers

I have this command line entry that I would like to turn into a script. I want to be able to just run the script with options for the report name and switch. Can anyone help me get started? I am hoping that by creating this script it will help me be able to create more.
I have never written one. I have read a few websites but can't find a really good one yet so if you know of any taht'd be great too.

Here is the command:
cat report.20060222 |grep Detroit | nawk -F"," '{tmp+=$10} END {print tmp}'

I want to just call the script total_rawfile.ksh

Then be able to run: total_rawfile.ksh report.20060222 Detroit


Thank you in advance for any help!

total_rawfile.ksh

Code:

cat $1|grep $2 | nawk -F"," '{tmp+=$10} END {print tmp}'

what did I do wrong?
I get this error:
ksh: total_rawfile.ksh: cannot execute

chmod +x total_rawfile

i am newer.

I am so dumb!
Ok now it works.

How can I put a line so that if someone types the script name it gives it it's usage. I tried this but it didnt' work:


function USAGE
{
echo "\nUSAGE: total_rawfile.ksh <report name> <switch short ID> \n"
echo "Here is an example:\n"
echo "total_rawfile.ksh RA_FW_SL4_rawfile_report.20070520.chk_SCOUT_ARCHIVE ANAJAL\n"
}

cat $1 | grep $2 | nawk -F"," '{tmp+=$10} END {print tmp}'
#grep $2
#nawk -F"," '{tmp+=$10} END {print tmp}'


Also let's say the variable has a / so like $1 is reports/daily is there anything special needed because the variable has a / in it?

thanks for the replies. And patience!

anyone?? I still dont know how to put usage?
