srpl

Search and Replace in large files using NodeJS & npm with RegExp without freeze ^^

Install

Usage

From any Terminal, CMD, powershell or other bash shell window

srpl my_db.sql '2017/12/(.*?).png' '2017/12/png/\$1.png' 'ig'

It should now create a copy of my_db.sql with all strings 2017/12/*.png replaced by 2017/12/png/*.png using flag ig, where * is a wildcard

Options

Takes 4 arguments (Last is Optional)

Arguments

1. source
2. search
3. replace
4. flag (Optional - Defaults to g)

Flags

If specified, flags can have any combination of the following values:

g global match; find all matches rather than stopping after the first match

i ignore case; if u flag is also enabled, use Unicode case folding

m multiline; treat beginning and end characters (^ and $) as working over multiple lines (i.e., match the beginning or end of each line (delimited by \n or \r), not only the very beginning or end of the whole input string)

u Unicode; treat pattern as a sequence of Unicode code points

y sticky; matches only from the index indicated by the lastIndex property of this regular expression in the target string (and does not attempt to match from any later indexes).
