try first:

dos2ux wor3e01_result.txt

then run the awk

when i try dos2ux i get following error message.
bash: command not found

also the output i like to see is below:

Item Version Part number CLEI code FRU model number
FPM Display REV 03 710-021387 CRAFT-TXXX-S

Code tags are not a "Unix thing". They're a forum thing. You got a PM about it. And a couple of infraction points with it.

try:

dos2unix wor3e01_result.txt

oK COOL....I WAS ABLE TO DO WHAT I WAS TRYING TO DO VIA USING GREP....WORKS FINE...BUT DO LIKE TO KNOW IF SAME CAN BE DONE USING AWK.

grep -A45 "Hardware" XXX.txt

or

cat xxx.txt | grep -A2000 "Hardware inventory" | grep -B2000 "Hardware inventory"

You can use

awk 'c-->0;$0~s{if(b)for(c=b+1;c>1;c--)print r[(NR-c+1)%b];print;c=a}b{r[NR%b]=$0}' b=2000 a=45 s="Hardware inventory" file

b=before
a=after

thanks to Franklin52 for this.

PS Turn of caps look when typing.

[b]dos2unix wor3e01_result.txt

$ awk '{ if ( $0 ~ "^Hardware inventory" ) { print; getline tmp; print tmp } } ' wor3e01_result.txt

Hardware inventory:
