I don't think the -U is portable enough:
| [EMAIL PROTECTED]:/u/rse
| $ /usr/bin/diff -U3 x y
| /usr/bin/diff: illegal option -- U
| usage: diff [-bitw] [-c | -e | -f | -h | -n] file1 file2
| diff [-bitw] [-C number] file1 file2
| diff [-bitw] [-D string] file1 file2
| diff [-bitw] [-c | -e | -f | -h | -n] [-l] [-r] [-s] [-S name]
directory1 directory2
The option -u on the other hand exists everywhere AFAIK.
Where did -u3 break?
