in reply to diff command
I do not understand what this means. 0a1,4 means
"a" denotes an addition. "d" denotes a deletion. The numbers on the left form a range of line numbers in file1. The numbers on the right form a range of line numbers in file2.
and how to make the output files identical
cp file1 file2
cp file2 file1
truncate -s 0 file1 file2
PerlMonks really needs a rating system like /. I would sooo cast my votes to mod up that reply funny. Thanks :)
These lines resemble ed subcommands to convert file1 into file2.
I prefer the unified diff format, it is usually easier to read than the traditional format. You can get that format with the -u parameter, i.e. diff -u old new (at least with GNU diff).
