Hi, i am novice to shells scripting. need help with one requirement i have

From my application, we extract a flat file in below format

something like this:

Code:
sed 's/Released|Onchange.*/Onchange/' input.txt

This will not change the file content itself. If this is needed, you may do inplace edit with -i option to sed.

Your specification does not match the output you gave, so it's difficult to supply a solution. Try (and adapt if need be)
Code:
 awk -F\| '/Onchange/ {NF=6; $6="Onchange"}1' OFS=\| file
TYPE_NM|NAME|REV|RELEASE_DT|TEC|CHANGE_STATUS|CHANGE_NM
HON4_SWPart|AMPLXSLTest1|-|2014-02-10T09:09:26|9E991|Onchange

Try :

bit robust

Code:
$ awk '/Onchange/{for(i=6;i<=NF;i++)if($i == "Onchange"){NF=6;$6="Onchange";break}}1' FS=\| OFS=\| file

Tested with

Code:
akshay@Aix:/tmp$ cat file
TYPE_NM|NAME|REV|RELEASE_DT|TEC|CHANGE_STATUS|CHANGE_NM
HON4_SWPart|AMPLXSLTest1|-|2014-02-10T09:09:26|9E991|Released|Onchange|Released|Released
HON4_SWPart|AMPLXSLTest1|Onchange|2014-02-10T09:09:26|9E991|Released|OnAchange|Released|Released

Resulting
Code:
TYPE_NM|NAME|REV|RELEASE_DT|TEC|CHANGE_STATUS|CHANGE_NM
HON4_SWPart|AMPLXSLTest1|-|2014-02-10T09:09:26|9E991|Onchange
HON4_SWPart|AMPLXSLTest1|Onchange|2014-02-10T09:09:26|9E991|Released|OnAchange|Released|Released
