[SOLVED] Printing different lines of a file from a script

TRUNoise · 11-06-2013, 09:28 PM

As the title would refer, I need a script to be able to read different lines and display the contents of each line.

For example; file "prop"

Code:

3G
server.jar

would be required from a script along the lines of

Code:

echo "====[ $(pwd) ]=====" #show what server it is
echo "server will run with $(cat prop;line1) of memory" #obviously not going to actually work but thats the concept
echo "server will run with jar file $(cat prop;line2)" #same comment as before

Before anyone asks, the 3G part is the memory the server will be started with and (obviously) the server.jar file is the actual server, which is written in Java.

Hope it's doable.

Hi,

are you asking how to select line number n from a text file? If so, you can use sed. For example, to select the 2nd line of the file "prop", you could do:

Code:

sed -n -e '2 p' prop

HTH,
