string manipulation

shellProgramming — Tue, 05 Aug 2008 16:04:12 GMT

How can I change
"Show 2008 -201" to "Show 2008-201"?
Basically, how can I remove the space before the "-".
Thank you

Hello shellProgramming,

Welcome to the HPUX Forums.

There are 100s of ways.

Here is one.

echo "Show 2008 -201"|sed -e s/\ -/-/g

Hi:

While I would use 'sed' (or Perl) for the transformation you show, if you want to use pure shell, you can do:

# echo Show 2008 -201|read A B C;echo "${A} ${B}${C}"

Regards!

In Shell programming there are always a lot of ways to do anything. Here's a way to do it in awk:
echo "Show 2008 -201"|awk -F" " '{ print $1" "$2$3 }

And one more (with search and replace):

echo "Show 2008 -201" | awk '{sub(/ -/,"-");print}'
