NAME

App::BashHistoryUtils - CLI utilities related to bash history file

VERSION

This document describes version 0.070 of App::BashHistoryUtils (from Perl distribution App-BashHistoryUtils), released on 2021-05-26.

DESCRIPTION

This distribution includes the following CLI utilities:

FUNCTIONS

delete_bash_history_entries

Usage:

 delete_bash_history_entries(%args) -> [$status_code, $reason, $payload, \%result_meta]

Delete matching entries from bash history file.

This function is not exported.

This function supports dry-run operation.

Arguments ('*' denotes required arguments):

  • histfile => str (default: "/home/u1/.bash_history")

  • ignore_case => bool

  • inplace => bool

    Replace original bash history file.

  • invert_match => bool

  • max_age => duration

    Match entries older than a certain age.

  • min_age => duration

    Match entries younger than a certain age.

  • pattern => re

    Match entries using a regex pattern.

  • strip_timestamp => bool

    Strip timestamps.

Special arguments:

  • -dry_run => bool

    Pass -dry_run=>1 to enable simulation mode.

Returns an enveloped result (an array).

First element ($status_code) is an integer containing HTTP-like status code (200 means OK, 4xx caller error, 5xx function error). Second element ($reason) is a string containing error message, or something like "OK" if status is 200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata.

Return value: (any)

each_bash_history_entry

Usage:

 each_bash_history_entry(%args) -> [$status_code, $reason, $payload, \%result_meta]

Run Perl code for each bash history entry.

This function is not exported.

Arguments ('*' denotes required arguments):

  • code* => str

    Perl code to run for each entry.

    Inside the code, you can set $PRINT to 0 to suppress the output of the entry. You can modify $_ to modify the entry. $TS (timestamp) is also available.

  • histfile => str (default: "/home/u1/.bash_history")

  • ignore_case => bool

  • invert_match => bool

  • max_age => duration

    Match entries older than a certain age.

  • min_age => duration

    Match entries younger than a certain age.

  • strip_timestamp => bool

    Strip timestamps.

Returns an enveloped result (an array).

First element ($status_code) is an integer containing HTTP-like status code (200 means OK, 4xx caller error, 5xx function error). Second element ($reason) is a string containing error message, or something like "OK" if status is 200.
