Search&Replace "Multi-line" text in multiple f

[mask_layout]

I am replacing a single line text with multiple line text. I will be doing this for about a hundred files and I think its crazy to work on it 1by1.

Im new to shell scripting in unix and cant get the following command to work on replacing single line to multiple lines.

#!/usr/local/bin/tcsh
foreach file (*.TECH)
   set newname=`basename $file .TECH`
   mv $file $newname"_DFM.TECH"
   end

foreach DFMfile (*_DFM.TECH)
  cat $DFMfile | perl -pi -e "s/OneLinerOldText/NewMultipleLineText/g;" >$DFMfile
end

This is my sample INPUT FILE

block "xxx"
{
line1 = 0
line2 = 0
OneLinerOldText = 0
line3
line4 }

NEW FILE I want to OUTPUT

block "xxx"
{
line1 = 0
line2 = 0
NewMultipleLine1
NewMultipleLine2
NewMultipleLine3
line3
line4 }

Can somebody help me to get this working please?

In Unix shell, if you write in command line

cat FILE | echo >FILE

Then you would got an empty file. Because they clear the FILE first.

Therefore, just use a intermidiate file to prevent the mistake:

#!/usr/local/bin/tcsh
foreach file ( *.TECH )
        set newname=`basename $file .TECH`
        mv $file $newname"_DFM.TECH"
end

set ext=.ext

foreach DFMfile ( *_DFM.TECH )
        cat $DFMfile | perl -pi -e "s/OneLinerOldText/NewMultipleLineText/g;" >$DFMfile$ext
        mv $DFMfile$ext $DFMfile
end

Hi wstu,

thanks for the reply.... ur script made it better... thanks thanks..

anyway, my real problem is that i cannot print in multiple lines... my output is always placed in a single line. I tried sed, grep and perl.... none works... or maybe i dont know the correct syntax...

im trying to use "\n" but it only prints as output.

's/oldonelinertext/new\nNew\nLiner\nText/g';

does not output

new
New
Liner
Text...
