grep file paths in each line of text 2

[RVSachin]

Hi,

My text file contains something like following:

adsdfaddfd <some path1>
adlfjakflafaf /<some path2>
adfabzlhzxhledfdfe3dfstet  <some path3>
d3dfstet  <some other path>

How do I print or redirect only the path information to another file?
That is, each line in second file should contain all the file paths found in file1

If possible, please include a note explaining the commands in your reply.

Thanks,

RV

sed 's/^[^ ]* //g' infile > outfile

Do you know sed?
It's an non-interactive stream-editor, which performs commands on input (optional: files, here 'infile') and prints to stdout, here redirected to outfile.

One of its commands is 's'=substitute.
s/pattern/replace/g
here we replace with nothing - ergo: we delete.
.../g: globally, not only once.

the pattern is encapsulated between slashes:
/^[^ ]* /
which means: ^ from beginning of line
[^ ] every character, which is not a space
* multiple times.

Or something like this ?
awk '{print $NF}' /path/to/input

Hope This Helps, PH.

Hi PHV,

Thanks for the solution.
Can you please let me know how this works?..I mean, what does NF do?

Thanks,

Ravi

In awk, NF is a builtin variable holding the number of fields of the current record and so, $NF is the last field.
