string characters in UNIX
I need some help.

when i use the following command, it deletes all lines containing WINNT& v2010 and WINNT& v2010.2

I just want it to delete lines containing WINNT & v2010 only.

perl -n -i.bak -e 'print unless /WINNT/&&/v2010/' *.*

Please give more clue : how look your input file ?

where can the v2010 located in the line ? beginning ? end ? before WINNT or after ?

same questions for the WINNT occurrence.

Code:
sed '/.*WINNT.*v2010[^\.].*/d;/.*v2010[^\.].*WINNT.*/d' infile

?

Assuming that there is a space on either side of "v2010":
Code:
perl -n -i.bak -e 'print unless /WINNT/ && /\sv2010\s/' *.*
