Hi guys,

Suppose I have the following strings:
test.yara.Z
and
test.yara

How can determine whether there is a something else specified after .yara? So, in the first case, there is another extension specified after yara?

Thank you!

From where? perl, sed, awk, sh, ksh, tcsh, csh, ...

Simple bourne sh!

tests $F for 2 dots + numbers
ie: 1.2.3 and returns VALUE=1:

echo $F | grep -E -q "^[0-9]+\.[0-9]+\.[0-9]+$" && VALUE=1

tests for just number:
echo $F | grep -E -q "^[0-9]+$" && VALUE=2

I'm sure you can work on it to remove the [0-9] for files.

This tests for extension xml:

if [ "${_Input#*.}" != "xml" ]; then
echo "xml"
fi

Hope that's a quick start
Later,
Bill

Hi:

Perhaps something like this:

#!/usr/bin/sh
X=`echo ${1##*.}`
if [ "$X" != "yara" ]
then
echo "...unexpected basename"
else
echo "...basename OK"
fi
#.end.

Regards!
