The scripts have calls to 'perf trace' that need to be converted to 'perf script', do it. This problem was introduced in 133dc4c.

perf trace/scripting: Enable scripting shell scripts for live mode

2010-04-14T09:56:08Z

It should be possible to run any perf trace script in 'live mode'. This requires being able to pass in e.g. '-i -' or other args, which the current shell scripts aren't equipped to handle. In a few cases, there are required or optional args that also need special handling. This patch makes changes the current set of shell scripts as necessary.

perf trace/scripting: List available scripts

2009-12-15T09:31:32Z

Lists the available perf trace scripts, one per line e.g.: root@tropicana:~# perf trace -l List of available trace scripts: workqueue-stats workqueue stats (ins/exe/create/destroy) wakeup-latency system-wide min/max/avg wakeup latency rw-by-file r/w activity for a program, by file check-perf-trace useless but exhaustive test script rw-by-pid system-wide r/w activity To be consistent with the other listing options in perf, the current latency trace option was changed to '-L', and '-l' is now used to access the script listing as: To create the list, it searches each scripts/*/bin directory for files ending with "-report" and reads information found in certain comment lines contained in those shell scripts: - if the comment line starts with "description:", the rest of the line is used as a 'half-line' description. To keep each line in the list to a single line, the description should be limited to 40 characters (the rest of the line contains the script name and args) - if the comment line starts with "args:", the rest of the line names the args the script supports. Required args should be surrounded by <> brackets, optional args by [] brackets. The current scripts in scripts/perl/bin have also been updated with description: and args: comments.

perf trace: Add a scripts/perl/bin for perf trace shell scripts

2009-11-28T09:04:27Z

To capture the relevant events for a given Perl script and to avoid having to continually remember and type in long command-lines, add a scripts/perl/bin directory containing two simple shell scripts for each Perl script, one for recording and one for processing/display. For example, to record perf data for the rw-by-pid.pl script, run scripts/perl/bin/rw-by-pid-record and to actually run the script and display the output run scripts/perl/bin/rw-by-pid-report.
