newcmp - compare sourcecode within two directory hierarchies
newcmp
[options] dir1 dir2
newcmp compares the files in two directory
hierarchies on a one-to-one basis using standard diff(1)
(or tkdiff(1)
, if
the -tk flag is given). Each file in dir1 is compared to its corresponding
file within dir2, but not the other way around. For this the program needs
to be re-run with the directory arguments swapped.
- -c
- count different
files, don’t difference them indivually. This will produce output as in:
Counted 5 / 23 files different
which means 23 files were found under dir1, of which 5 were found to be
different in dir2.
- -m
- also report missing files in dir2. Normally they are
sillently skipped. The will produce output as in:
Found 3 files that were not in ....
- -tk
- use tkdiff instead of diff.
- -s N
- start at difference file N instead of
1. Useful if you re-run the script and want to skip first N-1 differences.
- -1 list
- take dir1
diff(1)
, tkdiff(1)
