Accepting filename as command line param and writing to it

Hi,

Is it possible to accept a filename as command line parameter and then write to that file using command redirection? i tried the below script.

outputfile=`echo $1`

echo "Writing to file" > 'echo $outputfile'

exit $returncode


but it isnt working. is there any other way to write to a file whose filename is accepted as a parameter?

Try this:

Code:
outputfile=$1
echo $outputfile
echo "Writing to file" > $outputfile

Read some scripting tutorials or books.

Show your entire script. Have you make your script executable with chmod?
