trova

Introduction

trova is a simple directory recursive search tool ("trova" means "find" in Italian). It can be used as an alternative to utilities like "find" or "grep". It works on both Windows and Linux operating systems. It even has some limited support for doing text replacements or renaming/deleting files. By default, .svn or .git directories are excluded from searches (this can be overridden).

The repo also includes some extra bonus utilities (see below for details)

Prerequisites

Requires an up-to-date version of Perl. Tested using Strawberry Perl v5.30.0.

On Microsoft Windows you can use the 64-bit pre-compiled executable versions which do not require Perl to be installed. These can be found under Releases. In this case you can replace the .pl extension in the usage examples below with either .exe or nothing at all. This means you can simply type trova, confronta and quale to run the pre-compiled versions.

Examples

List all files in current working directory:

    trova.pl -n \.java

Search for foo in all .c files in src directory (but not .cpp files):

    trova.pl -n \.c$ -d src foo

Search for foo in all .dll files in lib directory, but only show number of matches:

    trova.pl -n \.dll$ -d lib foo -m

Search for foo in all .py files and replace with bar:

    trova.pl -n \.py foo -s bar

Search for red in all .py files with word boundaries, equivalent to "\bred\b" (avoids matches like redistribute, credit etc.):

    trova.pl -n \.py red -w

Search for memcpy in all .cpp|.h files and print number of lines in matching files:

    trova.pl -n ".cpp|.h" memcpy -c

Search for memcpy in all .cpp|.h files and print number of matches in each file:

    trova.pl -n ".cpp|.h" memcpy -m

Search for memcpy in all .cpp|.h files, but filter out lines beginning with "#":

    trova.pl -n ".cpp|.h" memcpy -m -f "^#"

    trova.pl -n ".cpp|.h" malloc -e free -el 10

Search for malloc in all .cpp|.h files which have free within +5 lines of it (below) and display number of extra matches and line numbers (use -ed=u to search upwards for extra matches):

    trova.pl -n ".cpp|.h" malloc -e free -el 5 -ed=d -l

Search for malloc in all .cpp|.h files which have free within the entire file and display number of extra matches and line numbers:

    trova.pl -n ".cpp|.h" malloc -e free -ed=a -l

quale.pl

This is a simple Perl replacement for which or where ("quale" means "which" in Italian). For more info run quale.pl --help.

This is a Perl script which generates a recursive call graph for Fortran code ("forte" means "strong" in Italian).
