NAME rafind2 -- advanced command-line byte pattern search in files SYNOPSIS rafind2 [-mBXnzZhqv] [-a align] [-b size] [-f from] [-t to] [-[e|s|S] str] [-x hex] [-E] [-F file] [-g] [-i] [-I str] [-j] [-L] [-M str] [-R str] [-r] [-c] [-V s:num | s:num1,num2] -|file|dir ... DESCRIPTION A versatile utility for searching byte patterns in files, supporting align- ment, offset ranges, string and hexadecimal queries, and customizable out- put formats. The following options are available: -a align Only accept aligned hits -b size Set block size -B Use big endian instead of little endian (See -V) -c Disable colorful output (mainly for for -X) -e regex Search for regex matches (can be used multiple times) -E Perform a search using an esil expression -f from Start searching from address 'from' -F file Read the contents of the file and use it as keyword -g Insert the replacement and resize the file (only with -R) -h Show help message -i Identify filetype (r2 -nqcpm file) -I str Filter files by rbin info (arch/type/bits/...) before searching -j Output in JSON -L List all IO plugins (same as r2 for now) -m Magic search, file-type carver -M str Set a binary mask to be applied on keywords -R str Replace each hit with the given string (prefix with h: hex, w: wide, s: string) -n Do not stop on read errors -r Print using radare commands -s str Search for a string (more than one string can be passed) -S str Search for a wide string (more than one string can be passed) -t to Stop search at address 'to' -q Quiet mode: fewer output do not show headings or filenames -v Show version information -V s:num | s:num1,num2 Search for a value or range in the specified endian (-V 4:123 or -V 4:100,200) -x hex Search for hexpair string (909090) with optional nibble mask using dots (41.42) (can be used multiple times) -X Show hexdump of search results -z Search for zero-terminated strings -Z Show string found on each search hit ENVIRONMENT rafind2 does not use any environment variables. EXAMPLES Search for a specific string in a file: $ rafind2 -s "search_string" file.txt Search for a hex pattern in all the files from directory: $ rafind2 -x "909090" directory_path Search for hex pattern with nibble mask (dot masks single nibble): $ rafind2 -x "41.42" file.bin Identify the file type: $ rafind2 -i binary_file Search for the little endian 123 stored in a 4-byte word: $ rafind2 -V 4:123 file.bin Search for a range of values (100-200) in a 4-byte word: $ rafind2 -V 4:100,200 file.bin Search for zero-terminated strings and show each string found: $ rafind2 -zZ file.bin Search using regex pattern: $ rafind2 -e "password|passwd" file.txt Show hexdump of search results: $ rafind2 -X -s "hello" file.bin Replace string hits in a file: $ rafind2 -s "old" -R "new" file.bin SEE ALSO radare2(1) AUTHORS pancake <pancake@nopcode.org> Feb 4, 2026 RAFIND2(1)
