How do I get sed to use variable values? 1

[markmulligansr]

I have this statement that uses sed

echo $tabname | sed 's/\_NEW/\_"${Month}"\_${Day}\_${Year}\_OLD/g' | read oldtabnamesuffix

The value of oldtabnamesuffix is tablename_${Month}_${Day}_${Year}_OLD after this statement executes.

Hoe do I get sed to use the variable values?

For example, I'd like to see oldtabnamesuffix's value be tablename_07_14_2010_OLD if today's date is 07_14_2010 and I put this into the $Month, $Day and $Year variables from the date command.

Thanks

echo $tabname | sed "s/_NEW/_${Month}_${Day}_${Year}_OLD/g" | read oldtabnamesuffix

Hope This Helps, PH.

[tt]$[/tt] has no meaning inside single quotes.

Try your sed command between double quotes

OR

"interrupt" your singly-quoted sed command string whenever you need to insert a shell variable

echo $tabname | sed 's/\_NEW/\_[red]'[/red]${Month}[red]'[/red]\_[red]'[/red]${Day}[red]'[/red]\_[red]'[/red]${Year}[red]'[/red]\_OLD/g'

and I think you're over-escaping characters \_ ???

echo $tabname | sed 's/_NEW/_[red]'[/red]${Month}[red]'[/red]_[red]'[/red]${Day}[red]'[/red]_[red]'[/red]${Year}[red]'[/red]_OLD/g'


HTH,
