String compare in multiple files
Hi
I have a requirement to process number of files matching a criteria. The resulted file would be processed indivdually looking for a particular string until another one found lines afterwards. Then look for the occurrence of another string in the result count and display/return the result.
Continue the process till the EOF reached then to take the next file do the same ... till no more files to process
example :
File1.log
######### AUD57#########
<:_:REQUESTSTRUCTURE>
<MESSAGE>.........
.............
.........
........
</ITEM>
.........
........
</ITEM>
.........
........
</ITEM>
.........
........
</ITEM>
</MESSAGE>
</:_:REQUESTSTRUCTURE>
................
.............
..............
..............
######### AUD57#########
<:_:REQUESTSTRUCTURE>
<MESSAGE>.........
.............
.........
........
</ITEM>
.........
........
</ITEM>
.........
........
</ITEM>
.........
........
</ITEM>
</MESSAGE>
</:_:REQUESTSTRUCTURE>
...........
EOF
So all I wanted to know is how many occaurcnce of </item> in this log file after "######### AUD57#########" and between "</:_:REQUESTSTRUCTURE>"
I have a kind of script which does this but takes ages to result (with process line by line). so would like to see a simpler and much faster solution - HELP please URGENT
cheers
