Shell Programming and Scripting

"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?)

should be korn shell

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?

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

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

thanks era, your method works however.


erm, i got another question though

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'?

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