hline

hline is a very small command line utility designed to highlight lines in log files. In practice, I've found that tuning the context that grep gives me when tail -fing a log can be quite cumbersome. Oftentimes, all I really care about is seeing that a certain message happened and some surrounding context. hline fills that niche!

Usage

hline 0.2.1
Highlights lines that match the given regular expression

USAGE:
    hline [FLAGS] <pattern> [filename]

FLAGS:
    -i, --ignore-case    Ignore case when performing matching. If not specified, the matching is case-sensitive.
    -h, --help           Prints help information
    -b                   Treat the given input file as text, even if it may be a binary file

ARGS:
    <pattern>     The regular expression to search for. Note that this is not anchored, and if anchoring is desired,
                  should be done manually with ^ or $.
    <filename>    The file to scan. If not specified, reads from stdin

Installation

cargo install hline
