将输出打印到linux中的文本文件中

Question

Hello I am trying to get the difference between to text files. There are a lot of differences and viewing them in terminal is making it volatile since I cannot save them. I want to view and save the diff. How would I catch the output and print it to a text file??

Code I am using for getting the diff is diff -i -w -B file1.txt file2.txt

Answer 1

Save to text file:

diff -i -w -B file1.txt file2.txt > diff.txt

Write directly to printer:

diff -i -w -B file1.txt file2.txt | lpr

Write saved text file to printer

lpr diff.txt

Answer 2

Generally speaking,
command > output.txt
and in your case
diff -i -w -B file1.txt file2.txt > output.txt

and if you want to append the result
command >> output.txt

Answer 3

Just redirect it to a file:

 diff -i -w -B file1.txt file2.txt > output.diff

If you'd like to know more about redirecting output, the advanced details vary shell-to-shell, but here's a reference for bash and a cheat-sheet for the common stdout/stderr redirects.
