fmerge(1) General Commands Manual fmerge(1)
NAME
fmerge - merge files
SYNOPSIS
fmerge [ option... ] basefile fileA fileB
fmerge -Help
fmerge -VERSion
DESCRIPTION
The fmerge program is used to compare the changes between two different descendants of a base file, and creates an output file which con-
tains both sets of changes. This is useful when two users both take the same version of a file and make independent edits to it, and then
later want to create a file which contains both sets of edits. In such a use, the original file that both sets of edits is derived from is
called the base file. The two files containing the edits are called file A and file B.
The command:
fmerge basefile fileA fileB -o outputfile
produces the output file which contains the edits contained in file A and file B, based on the base file . If the -Output option was not
used, or if no outputfile is specified, then the merged lines are typed to the standard output. The order of specifying file A and file B
is usually unimportant.
The fmerge program can also be used to remove earlier edits made to a module. To do this, make the version containing the edits you want
to delete be the basefile. Make the version previous to the edit you want deleted be file A. Finally, make the most recent version of the
file which contains the other edits (including the one you want deleted) be file B. Then the result of merging will be the newest version
of the module minus the changes made by the edit you wanted removed. For example, if three successive versions of some module have the
names edit10, edit11 and edit12, and you want the changes done by edit11 to be undone, but still want the changes done by edit12, then you
use the command:
fmerge edit11 edit10 edit12 -o outputfile
While merging the two sets of edits, fmerge may discover conflicts. A conflict occurs when the same line of the base file is changed by
both of the two sets of edits. The change can be due to new lines being inserted, lines being deleted, or both. When conflicts occur, the
output file contains conflict identification lines, which are lines containing the string '/-/-/-/'. These lines indicate the region where
the two sets of edits are incompatible. You must then edit the output file and remove these lines, and in addition correct the conflicts
manually in order to produce the correct result.
OPTIONS
The following options are understood:
-Conflicts [ conflictfile ]
Since conflicts due to deletions are invisible in the output file, and inserts do not specify which of the two edits inserted the
lines, there is an alternative output format from the fmerge program. This output format describes what happens to each line of
the base file, so that conflicts are easier to detect and fix. The command:
fmerge basefile fileA fileB -c conflictfile
produces the file describing the results of the merge in detail. If the -Conflicts option is specified without any conflictfile
name, then the conflicts are send to the standard output.
If there are conflicts, and the -Conflicts options is not specified, the fmerge program will exit with a status of 1.
The conflict file contains lines which contain three characters and then some text. The first three characters describe what is
happening to the base file at that point. These characters are the following:
IA This line was inserted by file A.
DA This line was deleted by file A.
IB This line was inserted by file B.
DB This line was deleted by file B.
<blanks>
This line is unchanged.
X This is a conflict identification line.
U There are unspecified unchanged lines here.
Each set of conflicts is flagged by three identification lines. The first line indicates the beginning of the conflict, and speci-
fies the line numbers for the base file and two divergent files. The second conflict identification line separates lines changed
by file A from lines changed by file B. The third conflict identification indicates the end of the conflict.
You can edit this conflict file to remove the conflicts. This involves deleting the conflict identification lines, and changing
the conflicting lines as necessary to fix the conflict. While doing this, remember to leave three blank characters at the front of
any new lines you insert while correcting the conflicts. When you are done, there should be no lines which begin with an 'X' in
the file. All other lines can remain. Then you can use the command:
fmerge conflictfile -o outputfile
to create the new output file which has the desired data. Once again, if no -Output option or outputfile is used, the output is
send to the standard output.
-Unchanged number
Besides physical conflicts, there can be logical conflicts. These are changes made to different lines in the base file such that
the program is no longer correct. Such conflicts cannot be detected by a program, and so these must be checked manually. In order
to make this process easier, the -Unchanged option can be used to reduce the size of the conflict file to only include regions near
changed lines. This file can then be examined in order to detect possible logical conflicts. As an example, the command:
fmerge basefile fileA fileB -c -u 3
will send to the standard output all changes made by either sets of edits, with only three unchanged lines surrounding each edit.
When using the -Unchanged option, the conflict file will contain lines starting with 'U'. These represent unchanged lines, and the
number following the letter is the number of unchanged lines. The resulting conflict file cannot be read to produce an output file
because of the missing lines. If this is attempted, an error will be generated.
It is possible to use both -Output and -Conflicts in the same command. Thus you can produce the output file which you hope is cor-
rect, and also produce the conflict file which you can use to check for logical conflicts.
-Verbose [ number ]
This option can be specified with any other action, and outputs status information about the progress of the action. This is use-
ful for debugging of problems, or just for amusement when the system is slow or a large file is being processed. It accepts a
numeric argument to indicate the verbosity for output. The levels are as follows:
0 No output at all (except for errors).
1 Single-line output describing action (default).
2 Detailed status as action proceeds.
-Failures number
This option restricts the number of physical conflicts that are allowed before failing. This is used if you are not interested in
the results if there are too many conflicts.
-Help
Give some help on how to use the fmerge program.
-Ignore
Ignore all conflicts.
-Ignore_Identical_Conflicts
The option may be used to suppress conflicts which make identical deletes, or identical inserts, or identical changes. This is
often desirable when merging two source code branches.
-VERSion
Show what version of fmerge is running.
All options may be abbreviated; the abbreviation is documented as the upper case letters, all lower case letters and underscores (_) are
optional. You must use consecutive sequences of optional letters.
All options are case insensitive, you may type them in upper case or lower case or a combination of both, case is not important.
For example: the arguments "-help, "-HELP" and "-h" are all interpreted to mean the -Help option. The argument "-hlp" will not be under-
stood, because consecutive optional characters were not supplied.
Options and other command line arguments may be mixed arbitrarily on the command line.
The GNU long option names are understood. Since all option names for fmerge are long, this means ignoring the extra leading '-'. The
"-option=value" convention is also understood.
FILE NAME EXPANSION
As a convenience, if a pathname begins with a period and a environment variable exists with that name, then the value of the environment
variable will be used as the actual pathname. For example, if a environment variable of .FOO has the value this.is.a.long.name, then the
command
fmerge -o .FOO
is actually equivilant to the command
fmerge -o this.is.a.long.name
If you want to prevent the expansion of a pathname which begins with a period, then you can use an alternate form for the pathname, as in:
fmerge -o ./.FOO
BINARY FILES
In general, fmerge can handle all text files you throw at it, even international text with unusual encodings. However, fmerge is unable to
cope elegantly with files which contain the NUL character.
The fcomp(1) program simply prints a warning, and continues, you need to know that it converts NUL characters into an 0x80 value before
performing the comparison.
The fmerge(1) program also converts the NUL character to an 0x80 value before merging, after a warning, and any output file will contain
this value, rather than the original NUL character.
The fhist(1) program, however, generates a fatal error if any input file contains NUL characters. This is intended to protect your source
files for unintentional corruption. Use -BINary for files which absolutely must contain NUL characters.
EXIT STATUS
The fmerge program will exit with a status of 1 on any error. The fmerge program will only exit with a status of 0 if there are no errors.
