The actual differing lines then follow. In the leftmost column, < (left angle bracket) indicates lines
from file1 and > (right angle bracket) indicates lines from file2.
For example, suppose that you want to quickly compare the following meeting rosters in the files
jan15mtg
and jan22mtg:
jan22mtg jan15mtg
alice alice
brent colleen
carole daniel
colleen david
daniel emily
david frank
emily grace
frank helmut
grace howard
helmut jack
jack jane
jane juan
juan lawrence
lawrence rusty
rusty soshanna
soshanna sue
sue tom
tom
You can use the diff command to compare jan15mtg with jan22mtg as follows:
$ diff jan15mtg jan22mtg
1a2,3
> brent
> carole
9d10
< howard
Here we find that Brent and Carole attended the meeting on January 22, and Howard did not.
We know this because the line number and text output indicate that brent and carole are
additions to file jan22mtg and that howard is a deletion.
In cases where there are no differences between files, the system returns your prompt. For more
information, see the diff(1) reference page either online or in the Open System Services Shell
and Utilities Reference Manual.
