UNIX for Dummies Questions & Answers

Hi, I need
to make some extraction . with the following input to get the right output.

input: /etc/exp/home/bin ====> output: exp

and

input: aex1234 ===> output: ex

Thanks for your help,

What did you try so far?

Two possible ways:

Code:

echo '/etc/exp/home/bin' | awk -F/ '{print $3}'
exp

Code:

echo 'aex1234'| sed 's/.\(..\).*/\1/'
ex

Hi,
thanks for you help,
with this solution:
echo '/etc/exp/home/bin' | awk -F/ '{print $3}'
exp.

do you have another solution with sed command? because when a try your first solution in a shell script having 3 input parmeters, the {print $3} take another value.

now i'm looking for a sed command, if this command can solve the problem.

Thanks

Totally depending on the new input. Show all kinds/possibilities of new input and I'll try to make it as generic as I can.

Hi,
I have a solution with awk.

#!/bin/ksh

cd `dirname $0`/
APPLIHOME=`pwd | sed 's%/[^/]*$%%'`
echo "$APPLIHOME"

if [[ $# -lt 3 ]] then
echo
echo "ERROR : need 4 parameters "
echo "ERROR : Syntax error: [$shellprog.sh FILE DB PACKAGE ENV] "
exit 3
fi
echo "echo ${APPLIHOME} | awk -F '/' '{print \$3}'" > temp
PARAM=`ksh temp`
echo $PARAM

I add to your awk solution [\] to the print option ==>{print \$3} and it work.

Thanks for your help,
