Command-line tools provide powerful text search and comparison capabilities on Unix and Linux systems. In particular, the diff and grep utilities are extremely popular for daily use. To add to the usefulness of output, try out the Context argument to view adjacent lines for reviewing text differences or matching grep items. Here is an example for 10 lines of context. Use the –help or man pages for more details on diff and grep context capabilities.
- diff -C 10 file1 file2
- grep -C 10 searchPattern fileName
