Extract specific lines from a file using a list of line numbers from another file

[BBAF]

Greetings list.

So, I have a file ("linefile") with ~600 line numbers in one column, e.g.

92
1433
1725
1821
10265

etc.

I want to extract the lines with these numbers from another file ("infile").

I think awk should be able to do the job, but can't figure out how. Any suggestions?

Cheers,
BBAF

yes, you are right. awk, (e)grep come to mind.

However, some more info is needed about the structure of that infile.
for example:
- do these numbers occur at the beginning of a line, when they occur?
- or do they occur in a certain row?
- do they occur before or after a certain char, i.e. "," or ":" ?

based on information like these, a RegularExpression can be created.
Right now, it's too vague.

Well ok, one can egrep for lines with numbers in it (like you wrote).
This would look like this:
egrep [0-9] infile

If there is at least one number in the line, it will match.
Regardless, where this number is or how often there is a number.

This is almost certain too much, I guess?

How about

for line in `cat linefile`; do sed -n "${line}p" infile; done

use grep with -f option

grep -f file1 file2
