context_range_get - Linux


context_range_get retrieves the specified context range from specified output. This command facilitates the querying of statistics and events associated with specific context ranges from computer system outputs, such as profiling data.


context_range_get <input_file> <range_start> <range_end>


  • input_file: Path to the input file containing the context ranges.
  • range_start: Start of the context range to be retrieved.
  • range_end: End of the context range to be retrieved.




Example 1: Retrieve a specific context range from a file

context_range_get profile.out 1000 2000

This command retrieves the context range from position 1000 to 2000 in the file "profile.out".

Example 2: Extract data from multiple context ranges

cat profile.out | context_range_get 1000 2000 | grep "function_name"

This command pipes the output of "profile.out" into context_range_get to extract and print all lines containing "function_name" within the specified range.

Common Issues

  • Incorrect range specification: Ensure that the specified range falls within the bounds of the input file.
  • File not found: Verify that the input file path is correct.
  • Invalid input file format: The input file should be in the correct format for specifying context ranges.


context_range_get can be integrated with scripts and other tools to automate the extraction and processing of context range data. For instance, it can be used in conjunction with data visualization tools to generate charts and graphs from the retrieved data.

Related Commands

  • context_dump: Dumps all context ranges from specified input.
  • context_diff: Compares context ranges from two input files.
