I've recently found some awesome replacements for common command line tools and wanted to share them and learn about others.
The three of these have made my recent troubleshooting much more efficient:
- ack - ack is a tool like grep, designed for programmers with large trees of heterogeneous source code
- dstat - replacement for vmstat, iostat, netstat, nfsstat and ifstat
- mtr - mtr combines the functionality of the 'traceroute' and 'ping' programs in a single network diagnostic tool
What tools do you install because they're better than the defaults?
