diffbl

Compares the contents of UCM baselines or streams

APPLICABILITY

ClearCase UCM (cleartool subcommand)

SYNOPSIS

diffbl [ -act·ivities ] [ -ver·sions ] [ -fir·st_only ]

{ baseline-selector1 | stream-selector1 }
{ baseline-selector2 | stream-selector2 }

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 or versions, or both.

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 that are not part of a baseline.

OPTIONS AND ARGUMENTS

SPECIFYING THE INFORMATION TO DISPLAY.   Default: Displays differences in terms of activities.

-act·ivities

Displays differences in terms of activities.

-ver·sions

Displays differences in terms of versions.

SELECTING THE OBJECTS TO COMPARE.

baseline-selector1

stream-selector1

Specifies an object 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 an object 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

Examples including 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 command interpreter prompt. In cleartool interactive mode, cmd-context represents the interactive cleartool prompt. In Attache, cmd-context represents the workspace prompt.

• Compare activities in two streams:

cmd-context diffbl stream:java_int stream:java_dev

<< deliver.java_dev.19990917.140443 "deliver java_dev on 09/17/99 14:04:43."

<< deliver.java_dev.19990917.141046 "deliver java_dev on 09/17/99 14:10:46."

• Compare baselines in two streams:

cmd-context diffbl -ver stream:java_int stream:java_dev

<< /vobs/parser/myfile.c@@/main/java_int/2

<< /vobs/parser/myfile.c@@/main/java_int/3
