Search text in one or more .zip, .jar, .ear, .war or .aar files, and even zip files nested within other zips, with the free ZZFind tool for Windows and Linux. Fully portable, no installation - runs from any USB stick.

Download the tool here:

The current version is 1.5.6 Revision 3, fixing startup error messages.

Type "zzfind" on the command line to get the following help text.

usage:
  zzfind [opts] zipname word1 [word2] [word3] ...
  zzfind [opts] -pat word1 [...] -dir zip1 [[!]*path] -file [!].ext1

    searches in .zip .jar .ear .war or .aar files, and in zip files
    embedded within other zip files, for words.

    if multiple words are given, then only areas containing ALL words
    are listed. the search is case insensitive by default.

    zzfind autodetects if a file content is text or binary. with binary,
    the distance between words must be <80 chars to be listed as a hit.

    file and search pattern syntax

    1. short form, easy but not very flexible:

       singlezipname word1 [word2 word3 ...]

          searches a single zip file for words.

    2. long form, more to type but very flexible:

       -pat word1 [...] -dir zip1 [zip2] [[!]*pathmask] -file fm1 [fm2]

       searches any number of zip files for patterns (words), but only
       - within subfiles having file mask fm1 or fm2 in their name
       - within subfiles having (not) pathmask in their path.

       "subfile" means a file within a zip file. a path mask is defined
       as a word with a wildcard "*" listed in the -dir section.
       path masks and file masks can be negated by !, for example,
       "-file !.bak" means "all files except .bak files".

    to learn all about the file selection syntax, it is recommended to
    download the free Swiss File Knife Base and type "sfk help select".

    options
    -text     process only text files, skip all binary files.
              finds words also over long lines, avoiding line breaks.
    -bin      do not autodetect file content, process all as binary.
              can also be used for floating text files (one linefeed per
              paragraph, not per line). may produce unwanted line breaks
              with short-lined text.
    -case     or -c activates case-sensitive search (not default).
    -lnum     list line numbers of hits.
    -nocol    disable color highlighting of output.
    -names    list only names of files containing at least one hit.
    -count    list no. of matching lines per file. implies -names.
              requires -text option, cannot be used with binary files.
    -quiet    do not show "scan" progress info.
    -pure     do not list filenames, list only text hits without indent.
              default when specifying a single file as first parameter.
    -verbose  tells in detail what find is actually searching for.

    pattern support:
       no wildcards or slash patterns are supported, with one exception:
       if you need to find patterns starting with "-" or "+", prefix
       them with backslash \ to avoid misinterpretation as options.

    return codes for batch files
       0 = no matches, 1 = matches found, >1 = error occurred.

    examples
       zzfind myzip.zip foo bar include
          search all files within myzip for the words foo+bar+include.

       zzfind -text myzip.zip foo bar include
          the same, but search only in text files, skipping binaries.

       zzfind -pat "class " -dir source.zip -file .h
          search all .h files within source.zip for pattern "class ".

       zzfind -pat "class " -dir x.zip *\include
          search for pattern "class " in all include directories of
          x.zip. note that the "*" marks \include as a path mask.

       zzfind -pat foosys -dir foo.zip bar.zip !*\depr -file .java
          within files foo.zip and bar.zip search for the word "foosys"
          but only within .java file contents that are NOT located 
          within a path starting with "depr" (e.g. \deprecated\).

 
How to search all .zip .tar .tar.gz .tar.bz2 of a folder

The commercial Swiss File Knife Extended Edition can search

  • all files of a folder, including all subfolders
     
  • including the contents of all contained .zip, .tar, .tar.gz and .tar.bz2 archive files
     
  • including archives embedded within other archives,
    like a .tar.bz2 within a .tar.gz within a .zip.

The free Swiss File Knife Base allows to create directory listings of all files and archives in a folder, and it contains a demo of deep archive search, reading the first 1000 bytes of each archive entry.
