Hi, i'm faced with this question, can anyone help me?

Search the file 'data' for all of the lines that contain the pattern 'uli101'and put those lines in the file 'matches'.

First, tell us from what environment you want this result. Second, post your best effort, describe the remaining problems and ask for help.

It looks like homework. What have you done so far to solve this problem?

OK--I closed the other one instead.....

As already stated, if you want help with your homework, you need to show us what you have done. Also, tell us what books and reference material you are using

and put those lines in the file 'matches'.

I have the same problem with the same question. Here is what I tried out:

tail data | head uli101 > matches

I have no clue how to do the question. I am using SSH

Pattern usually means inside a file .

There are some command --help that uses PATTERN for the filename .

In this case

Code:

grep -n -i -E 'uliXYZ|samanthaABC' /Path/To/File/Filename.txt

should do it .

head uliXYZ would return the first 10 lines of the file uliXYZ , not the content uliXYZ .

If you only want the first 10 lines use "grep -m 10" or "grep -A 10" .

Read "grep --help" and "man grep" .

You can also filter it through grep like

Code:

cat infile | grep 'uliXYZ'
