I ran diff with two files and got the following output:
1c1
< dbacaad
---
> dbacaad
What does this mean? My two files seem to be exactly the same. Thank you very much!
To answer the question you raised in the title: 1c1 indicates that line 1 in the first file was c hanged somehow to produce line 1 in the second file.
In practical terms: They probably differ in whitespace (perhaps trailing spaces, or Unix versus Windows line endings?).
Try diff -w file1 file2
, which will ignore whitespace. Or cmp file1 file2
, which
will tell you how many bytes into the file the first difference occurs.
