常用示例
Add timestamps
[command] | ts
Use ISO 8601 format
[command] | ts -i
Include milliseconds
[command] | ts -m
Use UTC time
[command] | ts -u
Show incremental time
[command] | ts -s
Show time elapsed
[command] | ts -i
Custom timestamp format
[command] | ts '[%Y-%m-%d %H:%M:%S]'
Convert existing timestamps
[command] | ts -r
说明
ts reads lines from standard input, prepends a timestamp to each line, and writes to standard output. It is part of the moreutils package and is useful for logging, debugging, and monitoring command output over time. The default timestamp format is "%b %d %H:%M:%S" (e.g., "Jan 22 14:30:45"). Custom formats use strftime conversion specifications. Extended specifiers %.S, %.s, and %.T provide subsecond resolution. The -s option shows cumulative time since ts started, useful for measuring total elapsed time. The -i option shows time between lines, helpful for identifying slow operations in pipelines. The -r option converts existing timestamps in the input to human-readable relative times, supporting many common timestamp formats.
