1.1 ! root 1: .TH UUDIFF 1C ! 2: .SH NAME ! 3: uudiff \- directory comparison between machines ! 4: .SH SYNOPSIS ! 5: .B uudiff ! 6: [ \-d ] ! 7: local-name remote-name ! 8: .SH DESCRIPTION ! 9: .I Uudiff ! 10: compares the files in the directory ! 11: .I local-name ! 12: and the directory ! 13: .I remote-name, ! 14: (where ! 15: .I remote-name ! 16: may be of the form ! 17: .I system-name!directory-name ! 18: and ! 19: .I system-name ! 20: is a ! 21: .I uucp ! 22: Unix name). ! 23: It reports (via mail) ! 24: which files are added, deleted, or changed, and provides ! 25: a ! 26: .I diff(1) ! 27: of altered printable files. ! 28: .PP ! 29: If a part of ! 30: .I remote-name ! 31: is omitted ! 32: (either the system or the directory) ! 33: the corresponding part of ! 34: .I local-name ! 35: is used. ! 36: If ! 37: .I local-name ! 38: is a file, rather than a directory, ! 39: .I remote-name ! 40: is also assumed to be a file and the program degenerates into ! 41: .IR diff(1) . ! 42: .PP ! 43: The option ! 44: .B \-d ! 45: does not diff altered files; only ! 46: the summary by file names is prepared. ! 47: .SH FILES ! 48: Lots. Files zz[abcdeglmn]????? are used for scratch space; ! 49: files brought back from the remote machine for ! 50: .I diffing ! 51: are stored (and left around) as ! 52: .I name.????? ! 53: and the final report is left in ! 54: .I uudiff.????? ! 55: (the exact name is reported by mail). ! 56: .SH "SEE ALSO" ! 57: diff(1), uucp(1) ! 58: .SH DIAGNOSTICS ! 59: Almost none. Anything more serious than misspelling ! 60: .I local-name ! 61: causes unpredictable and obscure results. ! 62: .SH BUGS ! 63: In addition to the standard ! 64: .I uucp ! 65: requirements a hook is needed at the remote ! 66: system, and at present is only installed ! 67: on the systems "research" and "inter". ! 68: .br ! 69: This program is written in shell and should be translated ! 70: to C so it could give diagnostics. ! 71: .br ! 72: Even if "remote-system" is the local system, uudiff ! 73: is subject to delays in uucp traffic. ! 74: .br ! 75: It should probably write the standard output, instead of insisting ! 76: on going into the background. ! 77: .br ! 78: Since checksums are used there is a probability of 1 in 2**32 ! 79: of missing differences between files. ! 80: .br ! 81: The ~userid syntax is not recognized.
