How do I strip trailing spaces from a variable? 1

[maalim]

I am accepting values for a variable outside of the script into an input field with fixed length. Since the value could have any length (max the input field length), I need a way of stripping trailing spaces if any, within the unix script.
Here's how I pass the value from the form to the script:
filen=`echo ${1}`

Any ideas?
Thanks.

That will do it!

That will do it, but it's overly complicated. This would be better...

filen=${1}

That transfers your value and removes any trailing spaces.

Hope this helps.

I should have added this earlier:
the value passed to the script is uppercase. I need to convert it to lowercase and append the directory in which the file is located: Example
filen = ${1} results in PR197-123.CSV. I need it to read 'pr197-123.csv. Additionally, the file is to fetched from directory /xfer/interface and passed to sqlloader for instance; it should read '/xfer/interface/pr197-123.csv'.
How do I achieve this?

Thanks.

And what about something like this ?
typeset -l filen=/xfer/interface/$1

Hope This Helps, PH.

SamBones: Your solution does not work!

$ cat r0
#!/bin/ksh
var1=`echo ${1}`
var2=$1
echo "\$1=[$1]"
echo "\$var1=[$var1]"
echo "\$var2=[$var2]"
$ r0 "Foo   "
$1=[Foo   ]
$var1=[Foo]
$var2=[Foo   ]
$

PHV, Your solution does not remove trailing spaces either:

$ cat r0
#!/bin/ksh
typeset -l filen=/xfer/interface/$1 
echo "filen=[$filen]"
$ r0 "FOO-BAR.CSV   "
filen=[/xfer/interface/foo-bar.csv   ]

How about:

filen="/xfer/interface/`echo ${1}|tr [:upper:][:lower:]`

LKBrwnDBA, my preference would be:
typeset -l filen=/xfer/interface/$(echo $1)

Hope This Helps, PH.

And this?

eval typeset -l filen=/xfer/interface/$1
