Help need in modifying the text of .txt file
Hi All,

I've written a shell script in which i defined two varibles

for example:

str=1.0.0.15
timeStamp=2008.03.08

now using this varibles i need to modify a text file.

The text content looks like this

************************
* packageNumber : 1.0.0.14 *
* date : 2008.02.08 *
************************

after executing the shell script, the text must look like this

************************
* packageNumber : 1.0.0.15 *
* date : 2008.03.08 *
************************


Could anybody help me in resolving this issue?

Thanks,
Vinna

Bug
I'm sure someone will have a better way of achieving this but here's one version:

~/scripts/play % cat file1
************************
* packageNumber : 1.0.0.14 *
* date : 2008.02.08 *
************************


~/scripts/play % cat aa
Code:
#!/bin/sh

str=1.0.0.15
timeStamp=2008.03.08
file=${HOME}/scripts/play/file1

rep1=`grep packageNumber ${file} | awk '{print $4}'`
rep2=`grep date ${file} | awk '{print $4}'`

sed -e 's/'"${rep1}"'/'"${str}"'/' -e 's/'"${rep2}"'/'"${timeStamp}"'/' $file > ${file}.tmp
mv ${file}.tmp $file

~/scripts/play % aa
~/scripts/play % cat file1
************************
* packageNumber : 1.0.0.15 *
* date : 2008.03.08 *
************************
~/scripts/play %

Tools Made a couple of assumptions, but it works
Assumed that the packageNumber was always eight characters and date was always ten characters in length. Hence the 8 and 10 in my command below.

Code:
> cat sample2
************************
* packageNumber : 1.0.0.14 *
* date : 2008.02.08 *
************************
> echo $str
1.0.0.15
> echo $timeStamp
2008.03.08
> cat sample2 | sed "s/date : .\{10\}/date : $timeStamp/" | sed "s/packageNumber : .\{8\}/packageNumber : $str/"
************************
* packageNumber : 1.0.0.15 *
* date : 2008.03.08 *
************************
