how to grep a exactly string?

[Stanley_8]

hi~

If I grep "ABC",
I will receive the result like follows:

ABC
ABCD
ABCDEF

If I only want the result "ABC" return, how does it do?

[Franky Leeuwerck_1]

Hi,

You can use : grep "ABC "

grep "ABC$"

[Stanley_8]

No..
It's not working!

ex:
#ps -ef|grep "ABC"

It will return all the line contain "ABC".
I want it return include "ABC" exactly.
Not "ABCD" or "ABCDEFR".

Hi~

grep "ABC$" is not working too.

I can't find anything.

Hi Stanley,
quite tricky. On 11.11 and onwards you can use the grep -w ABC for an exact match. On older versions you have to define something that makes it distinctive from the other possibilities, e.g.:
# grep ABC infile1 | grep -v "[D-Z]

but what can be used will depend on the situation.

Hi Stanely

[Stefan Farrelly]

Very trickey. Im not sure even grep -w will do it for you. You must define more the rules under which you want to find ABC - at the start of the line ? end of line ? with blanks either side of it ? etc.

Try this;

ps -ef|awk '{print $9}'|grep -x ABC

But this will only work if the command part of ps has ABC only on it - nothing else, not /bin/ABC or ABCD etc.

Hi Stanely

grep -w ABC

l1:/tmp 103 > cat xx
ABC
AABC
ABCC
ABC
CBA
ABCD
ABCDE
ABC DEF
FABC D
l1:/tmp 104 > perl -ne '/\bABC\b/ and print' xx
ABC
ABC
ABC DEF
l1:/tmp 105 >

hi,

grep -x ABC

hi Stanely,
As Ravi said, grep -x will do the trick.

from the man page
---
-x (eXact) Matches are recognized only when the
entire input line matches the fixed string or
regular expression.
---

Is this what you are looking for

my OS version is 11.00.
no "-w" function included.

I use "ps -ef" command and I want to grep the user name and the other information.
so I can't use the option "-x" to grep full line.
I try to use "awk" but only can find the user name . the other information was cut.

(grep -V)

# ps -fu203

gives you all the processes of user 203

# ps -ef

gives you *all* processes

"And other information" is much to vague for us to solve

Attached is a perl script that mimics ps behaviour (without using 'ps') and runs on HP-UX and AIX. Easy to modify to get other fields or info

Hi,

Perhaps try it in another way ...

ps -fu login

Regards

[Umapathy S]

hi Stanley,
The best alternate is to try ps -fu ABC instead of ps and grep.
