It has grown tremendously. It has become another Perl -- a language used not because people particularly like or need its features, but because "it's got a library for <something>". But it does have the advantage of not being Perl.

How many non-library files does a language need to open, to sit there and do nothing?

Code:

$ strace python /dev/null 2>&1 | grep "^open" | egrep -v 'ENOENT|[.]so' | wc -l
42

$ strace php /dev/null 2>&1 | grep "^open" | egrep -v 'ENOENT|[.]so' | wc -l
6

$ strace bash /dev/null 2>&1 | grep "^open" | egrep -v 'ENOENT|[.]so' | wc -l
5

$ strace perl /dev/null 2>&1 | grep "^open" | egrep -v 'ENOENT|[.]so' | wc -l
3

$ strace awk '{}' /dev/null 2>&1 | grep "^open" | egrep -v 'ENOENT|[.]so' | wc -l
3

XZGREP(1)							     XZ Utils								 XZGREP(1)

NAME

       xzgrep - search compressed files for a regular expression

SYNOPSIS

       xzgrep [grep_options] [-e] pattern file...
       xzegrep ...
       xzfgrep ...
       lzgrep ...
       lzegrep ...
       lzfgrep ...

DESCRIPTION

       xzgrep  invokes	grep(1)  on  files  which may be either uncompressed or compressed with xz(1), lzma(1), gzip(1), or bzip2(1).  All options
       specified are passed directly to grep(1).

       If no file is specified, then standard input is decompressed if necessary and fed to grep(1).  When reading from  standard  input,  gzip(1)
       and bzip2(1) compressed files are not supported.

       If  xzgrep  is  invoked as xzegrep or xzfgrep then egrep(1) or fgrep(1) is used instead of grep(1).  The same applies to names lzgrep, lze-
       grep, and lzfgrep, which are provided for backward compatibility with LZMA Utils.

ENVIRONMENT

       GREP   If the GREP environment variable is set, xzgrep uses it instead of grep(1), egrep(1), or fgrep(1).

SEE ALSO

       grep(1), xz(1), gzip(1), bzip2(1), zgrep(1)
