UNIX for Dummies Questions & Answers

Hi,

I have two files in an html folder I would like to compare using diff. However I would like to append those files to a text file that is two folders up in my directory. Every time I try to do this I lose my information. What is happening and what should I do?

Is the file you are appending to a log file or is it that you want then changes to appened to a HTML file?

Can you show us what you are currently doing?

here is kind of what I am working on, but I know it is incorrect somehow

diff (compare oldpage1.html with newpage2.html) append to notes.txt

here is the code sort of

diff oldpage1.html newpage2.html >> notes.txt

I haven't tried the >> yet because I don't know if it will erase/disappear everything or not but this looks like the closest to working code. Thank you again for helping.

The >> operator will append the output to your notes.txt file. Neither file will being impacted by the diff command. If you are worried about erasing the contents of the notes.txt file, then simplly redirect to a new file while you sort out your issues. The > operator will over write the existing file (if it exists) with the contents of the redirection, otherwise it will create a new file containing the contents of the redirection.
