function::nsecs_to_string - Linux
Overview
function::nsecs_to_string converts nanoseconds to human-readable string representations. It’s a powerful tool for transforming timestamps into comprehensible formats.
Syntax
nsecs_to_string(nanoseconds, granularity=6, short=False)
Options/Flags
- granularity: Sets the output precision in milliseconds (ms). Defaults to 6 (microsecond precision). Valid values are:
- 0: nanoseconds (ns)
- 3: milliseconds (ms)
- 6: microseconds (µs)
- 9: nanoseconds (ns)
- short: Shorten the output string where applicable (e.g., "123 µs" instead of "123.000 µs").
Examples
Example 1: Convert to Microseconds
nsecs_to_string(1234567890) # Output: "123.457 ms"
Example 2: Convert to Milliseconds with Shortened Output
nsecs_to_string(987654321000, granularity=3, short=True) # Output: "98.765 s"
Example 3: Convert to Nanoseconds
nsecs_to_string(1234567890123, granularity=0) # Output: "123,456,789 ns"
Common Issues
Issue: Output string is too precise or cluttered.
Solution: Adjust the granularity parameter to the desired level of detail.
Issue: Output string is not in the expected format.
Solution: Ensure that the correct granularity and short options are used.
Integration
function::nsecs_to_string integrates seamlessly with other timestamp manipulation commands, such as function::timestamp_now and date.
Example: Convert Timestamp to Human-Readable Format
timestamp=$(function::timestamp_now)
human_string=$(function::nsecs_to_string ${timestamp})
echo "Current time: ${human_string}"
Related Commands
