Hi:

# grep thestring filename

For example, if you want to find the string "host" in the file '/etc/hosts' you would do:

# grep hosts /etc/hosts

See the man pages for 'grep'.

Regards!

You can use grep, or cat and pipe to awk.

Hi,

One way to find a string in a file is with the 'grep' command:

grep somestring filename

Do a 'man grep' and take a look at the docs. There are lots of regular expressions you can use for finding strings.

Hi,

two possibilities:

grep -i 'string' *
gives you the filename and the line with the string.

If you edit a file with vi:
/string 'enter'
get the curser to the string.

More questions?

Depends...

If you're at a prompt -
grep "string" /path/to/filename

If in "vi" -
/string will take you to the first occurence of the string, "n" takes you to the next.

freshman huh? welcome to the free world.

grep is the tool you need to study.

grep -v something *

will print all the lines in all the files in the present directory, EXCEPT the lines that contain "something" - cool right?

grep -E "name && lastname" filename

will get name and lastname out of a file.

grep -E "name || lastname" filename

will get either name or lastname out of the file.

enough from the peanut galary -

hack away - peace

Here's a fun one.

Want to find a text string in a file, but do not know which file or where to look?

cd to root - cd /
and type:

find . -type f -exec grep -l '' {} \;

Has been invaluable for me at times.

Note: Can be a resource hog and take a long time if you have a substantial filesystem.

Enjoy HP-UX!

You can also use the command "strings" to find text strings in a binary file.

This is useful when looking for error messages, or other messages, when you don't have source code.

Again, this usually gets piped through grep...

strings | grep

By the way, none of these answers is specific to hp-ux, they'll work with any unix/linux system.

Enjoy!
