SYNOPSIS
- Display
differences between two baselines or streams nongraphically:
- Display
differences between the specified baseline and its predecessor
baseline nongraphically:
- Display
differences between two baselines graphically:
- Display
differences between the specified baseline and its predecessor baseline graphically:
DESCRIPTION
The diffbl command compares the contents of two baselines or streams and displays any differences it finds. You can choose to see differences in terms of activities, versions, and for composite baselines, members.
You can use the diffbl command to compare a baseline and a stream, a baseline and a baseline, or a stream and a stream. When specifying a stream, all baselines in the stream are used in the comparison as well as any changes in the stream that are not yet captured in a baseline.
The diffbl command must be issued from a view context to display versions.
OPTIONS AND ARGUMENTS
Specifying the Information to Display
- Default
- –activities
- –act·ivities
- Displays differences in terms of activities.
- –ver·sions
- Displays differences in terms of versions.
- –bas·elines
- For composite baselines, displays differences
in terms of member baselines. When used with the –activities option,
displays each member baseline followed by activities in the member baseline.
- –fir·st_only
- Shows only those changes that appear in the
first object specified for the comparison.
- –nre·curse
- For composite baselines, displays differences
between the named baselines themselves and not between their members.
Selecting the Objects to Compare
- Default
- None.
- baseline-selector1 , stream-selector1
- Specifies objects to use in the comparison.
baseline-selector is of the form: [baseline:]baseline-name[@vob-selector] and vob is the baseline's UCM project VOB. stream-selector is of the form: [stream:]stream-name[@vob-selector] and vob is the stream's UCM project VOB.
- baseline-selector2, stream-selector2
- Specifies objects to use in the comparison.
baseline-selector is of the form: [baseline:]baseline-name[@vob-selector] and vob is the baseline's UCM project VOB. stream-selector is of the form: [stream:]stream-name[@vob-selector] and vob is the stream's UCM project VOB.
EXAMPLES
The UNIX examples in this section are written for use in csh. If you use another shell, you may need to use different quoting and escaping conventions.
The Windows examples that include wildcards or quoting are written for use in cleartool interactive mode. If you use cleartool single-command mode, you may need to change the wildcards and quoting to make your command interpreter process the command appropriately.
In cleartool single-command mode, cmd-context represents the UNIX shell or Windows command interpreter prompt, followed by the cleartool command. In cleartool interactive mode, cmd-context represents the interactive cleartool prompt.
Note: In the UNIX examples that follow, arguments and output that show multicomponent VOB tags are not applicable to ClearCase LT, which recognizes only single-component VOB tags. In this manual, a multicomponent VOB tag is by convention a two-component VOB tag of the form /vobs/vob-tag-leaf—for example, /vobs/src. A single-component VOB tag consists of a leaf only—for example, /src. In all other respects, the examples are valid for ClearCase LT.
