Linux Box

I need a good linux OS that would run on 256MB of RAM or less. & with CPU 1GB.

I have Xubuntu on my old desktop works good

I am new to linux and have been trying to figure this out forever for a homework assignment! I am supposed to use appropriate linux commands to capture all "C or CPP" files in the linux operating system and make a list of the files. I am using Xubuntu. I am a beginner and could use any advice! Thanks!

What does it mean to capture a file??

If you mean to find the files and list the results, use the ‘find’ command to search for *.c and *.cpp files in the whole system. You will get the result on the screen, and you can redirect the output to a file.

To find *.c files:
find / -name *.c

To find *.cpp files:
find / -name *.cpp

Explanation: the "/" means to start the search at the top of the file system, meaning that the search will include all the system. The "-name" means to search by name, and "*.c" is the file pattern you want to find.

To redirect the output, use "> output_file" for example:
find / -name *.cpp > output_file

Hope it helps. See the manual page ‘man find’ to learn more.
