i want to remove both the line starting with "=" and "(" but i can only remove one at a time..so how do I go about removing both of them?

One way:

Code:

awk  '!/^\=+/ && !/^\(/ '  your_file

Annihilannic · #3 (**permalink**) 05-15-2008

Something like this?

Code:

grep -v '^[(=]' inputfile > outputfile

finalight · #4 (**permalink**) 05-15-2008

now i got another problem

my dashes "---" "---" are not at the first line, and iwant to remove them as well
however when i try to do this:

Quote:

grep -v '[=-(]' test.txt

it won;t remove the dashes at all

can you please explain the pattern to me?

and it says event not found

rubin · #6 (**permalink**) 05-15-2008

To remove the dashes too, use:

Code:

awk '!/^\=+|^\(|^\-+/' your_file

If your OS doesn't recognize awk , try nawk or /usr/xpg4/bin/awk on solaris.

finalight · #7 (**permalink**) 05-15-2008

it recognizes awk, but it doesn't recognizes '/^\' this particular pattern

era · #8 (**permalink**) 05-15-2008

"Event not found" is a message from your shell. You need to use different quoting (though I don't understand how it could say that if you use single quotes; which shell are you using?)

finalight · #9 (**permalink**) 05-15-2008

should be korn shell

era · #10 (**permalink**) 05-15-2008

If you are on Solaris or HP-UX, did you try looking for nawk or XPG4 awk?

The grep command above should work, as such. The dash between = and ( in the command you tried seems misplaced; does it help if you take it out? How exactly is the result wrong?

finalight · #11 (**permalink**) 05-15-2008

Quote:

grep -v '[=-(]' test.txt

you mean this?

my dashes are not at the first position, in fact it's a certain distance away from the 1st position of the line, having some spaces in between

when i do that command above, it still doesn't remove the dashes, that's all

era · #12 (**permalink**) 05-15-2008

That command should remove any line which contains an equals sign, or an opening parenthesis; the dash you put between also causes it to remove all lines which contain a character whose ASCII code falls between those two, in theory; however, ( comes before = in ASCII so I guess it doesn't really change anything (but could also be the reason you're not getting it to work). Take out the dash and try again? Or move it first or last in the class, like

Code:

grep -v '[-=(]' file

finalight · #13 (**permalink**) 05-16-2008

thanks era, your method works however.

erm, i got another question though

Quote:

xxx 254 xx 40 HC M U02 25 6 4 0
*space* xx 20 GP H U02 27 3 1 0
*space* xx 20 GP U U02 27 3 1 0
*space* xx 40 HC X U02 25 4 3 0
*space* xx 40 HC U U02 25 6 1 0
*space* xx 20 GP L U02 27 3 1 0

the file indentation for that part is actually like that as of above (well almost, the xx is align with the xx). However, different files has different number of line for that.
However, after the data is done showing, the next line will always be a empty space (or "\n" if what you guys call it)

so how do I extract those data and ignore the 'x254'?

era · #14 (**permalink**) 05-16-2008

Different question, different thread. Also try to explain it better. "Before" and "after" samples are often instructive.

finalight · #15 (**permalink**) 05-16-2008

oh ok, I go create another thread
