A simple ZNC search script.

search.bash

#!/bin/bash
## search.{bash,zsh} v0.0.3

## Configuration
LOG_DIR=~znc/'.znc/moddata/log/syrup-tan';
DEFAULT_SERVER='rizon';

## Usage
## Source the file with $ . ./search.bash
##  All queries must begin with a from_* function
##  e.g. from_buffer '#r/a/dio' | grep_nick 'DigitalHoarder' | grep_pattern '\.(jpg|png|gif)' | count;
##  e.g. from_server 'rizon' | grep_nick 'Indago' | count;

## Queries
##  from_buffer $BUFFER [$SERVER]   – Outputs all logs from $BUFFER
##  from_server [$SERVER]           – Outputs all logs from $SERVER
##   | grep_nick $NICK              – Filters messages that weren't sent by $NICK
##   | grep_pattern $PATTERN        – Filters messages that don't match $PATTERN
##   | count                        – Outputs the number of messages found

## Get all of the logs from a server
from_server() {
    
    ## TODO: Find out if this needs to be lowercase
    SERVER="$1";
    if [ -z "$SERVER" ]; then
        SERVER="$DEFAULT_SERVER";
    fi;
    
    ## Cat all of the log files
    ## Requires multiglob support
    cat "$LOG_DIR"/"$SERVER"/**/*'.log';
    
}

## Get all of the logs from a buffer
from_buffer() {
    
    BUFFER="$1";
    ## Strip bad characters & convert to lowercase
    BUFFER="$(
        echo -n "$BUFFER" |
            tr -c '[[:alnum:]]#._' '-' |
            tr '[[:upper:]]' '[[:lower:]]';
    )";
    
    SERVER="$2";
    if [ -z "$SERVER" ]; then
        SERVER="$DEFAULT_SERVER";
    fi;
    
    ## Cat all of the buffer logs
    cat "$LOG_DIR"/"$SERVER"/"$BUFFER"/*'.log';
    
}

## Grep all of the logs from a nick
grep_nick() {
    
    ## Get the nick
    NICK="$1";
    
    ## Grep the nick from stdin
    grep '^\[.\{8\}\] <'"$NICK"'>' /dev/stdin;
    
}

## Pretty grep
grep_pattern() { grep -E "$1" /dev/stdin; }

## Pretty wc -l
count() { wc -l /dev/stdin | cut -d ' ' -f 1; }
