another questions:

i have two variables:
var1="string1"
var2="string2"


i want run the grep command which will enable to add '|' (pipeline) in it.
for instance
result = `grep LOGIN $var1 | grep ${var2} | awk -F"|" '{ print $4}'`
result2= ${result}

I keep getting errors, what do i have to do?????


Daniel

Can you show what error are you getting?

Read the earlier posts, and don't make the same errors that were pointed out to you before, i.e., there should be no spaces around '='.

Then make sure that your grep commands are correct (e.g., that the pattern precedes any file names), and quote your variables when you expand them, not when you assign values to them (unless there are special characters in the values).

hello again,

A little problem,
when i am running a grep function and forwarding it to a new file
"grep STRING FILE1 > FILE2"
in the begining of the new file (FILE2) i get binary code and then the output of the result.

meaning, i get this letter:
"@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@ ^@^@^@^@^..."

how can i avoid it?

Does this always happen, no matter what file you are grepping?

If so, you have a corrupted grep; replace it.

If not, you have a corrupted file; fix it.

when i run a grep and put the result in a file (in the prompt mod) everything is okay and i dont that problem.
but I have written a script that when running it , it does the following:

1. backups the log file (that one that is written into)
2. creating a new tmp file
3. searching the file using grep

when looking inside the new grep file i have this problem.
