NAME
changes − Run filemerge on two versions of an sccs file
SYNOPSIS
changes [-iaw] file
DESCRIPTION
This program invokes filemerge to compare two versions of a file under sccs control. If neither option -i nor -a is specified, the program picks what appear to be the two most recent versions. That is, if the file is checked out, the current version is compared to the latest delta. If the file is not checked out, the latest two deltas are compared.
If -i (interactive) is specified, some recent delta commentary is displayed and the user is prompted for the old and new versions, which default as described above. Option -a (all) is similar, except that all of the delta commentary is shown, using a pager such as "more".
Ordinarily filemerge is invoked in read-only mode. Option -w (write) causes filemerge to be invoked normally, so that the files can be merged.
ENVIRONMENT
The environment variable PAGER is used as the executable through which to pipe sccs prt output if option -a is specified. If PAGER is not set, "more" is used.
