Linux grep command

Question

Can I use grep command to look for all the lines in a file that have"abc" in them, but exclude the lines that end in say "xyz"?

Eg grep 'abc' fileName (some way to exclude all lines ending in "xyz")

Answer 1

Try this:

hzhang@dell-work ~ $ cat sample.csv 
abc, xyz
abc,1
abc,2
abc,3,xyz
hzhang@dell-work ~ $ grep abc sample.csv |grep -v "xyz$"
abc,1
abc,2

The explanation of -v:

-v, --invert-match
              Invert the sense of matching, to select non-matching lines.  (-v is specified by POSIX.)

If you can use awk, just check the patterns:

hzhang@dell-work ~ $ awk '/abc/ && !/xyz$/' sample.csv 
abc,1
abc,2
