Code:
tr -d '[ ]' < in_file | tr '[,]' '[\n]' > out_file

That was for ranges, not for enumerated strings of characters..

Quote:
On historical System V systems, a range expression requires enclosing square-brackets, such as:

tr '[a-z]' '[A-Z]'

However, BSD-based systems did not require the brackets, and this convention is used here to avoid breaking large numbers of BSD scripts:

tr a-z A-Z

The preceding System V script will continue to work because the brackets, treated as regular characters, are translated to themselves. However, any System V script that relied on "a-z" representing the three characters 'a', '-', and 'z' have to be rewritten as "az-".
tr: rationale

In fact, using brackets that way will also delete square brackets:
Code:
$  echo 'x[  ]x' | tr -d '[ ]'
xx

zipgrep

ZIPGREP(1L)															       ZIPGREP(1L)

NAME

       zipgrep - search files in a ZIP archive for lines matching a pattern

SYNOPSIS

       zipgrep [egrep_options] pattern file[.zip] [file(s) ...]  [-x xfile(s) ...]

DESCRIPTION

       zipgrep	will  search  files  within  a ZIP archive for lines matching the given string or pattern.  zipgrep is a shell script and requires
       egrep(1) and unzip(1L) to function.  Its output is identical to that of egrep(1).

ARGUMENTS

       pattern
	      The pattern to be located within a ZIP archive.  Any string or regular expression accepted by egrep(1) may be used.  file[.zip] Path
	      of  the  ZIP archive.  (Wildcard expressions for the ZIP archive name are not supported.)  If the literal filename is not found, the
	      suffix .zip is appended.	Note that self-extracting ZIP files are supported, as with any other ZIP archive; just	specify  the  .exe
	      suffix (if any) explicitly.

       [file(s)]
	      An  optional list of archive members to be processed, separated by spaces.  If no member files are specified, all members of the ZIP
	      archive are searched.  Regular expressions (wildcards) may be used to match multiple members:

	      *      matches a sequence of 0 or more characters

	      ?      matches exactly 1 character

	      [...]  matches any single character found inside the brackets; ranges are specified by a beginning character, a hyphen, and an  end-
		     ing character.  If an exclamation point or a caret (`!' or `^') follows the left bracket, then the range of characters within
		     the brackets is complemented (that is, anything except the characters inside the brackets is considered a match).

	      (Be sure to quote any character that might otherwise be interpreted or modified by the operating system.)

       [-x xfile(s)]
	      An optional list of archive members to be excluded from processing.  Since wildcard characters  match  directory	separators  (`/'),
	      this  option  may  be used to exclude any files that are in subdirectories.  For example, ``zipgrep grumpy foo *.[ch] -x */*'' would
	      search for the string ``grumpy'' in all C source files in the main directory of the ``foo'' archive, but none in any subdirectories.
	      Without the -x option, all C source files in all directories within the zipfile would be searched.

OPTIONS

       All options prior to the ZIP archive filename are passed to egrep(1).

SEE ALSO

       egrep(1), unzip(1L), zip(1L), funzip(1L), zipcloak(1L), zipinfo(1L), zipnote(1L), zipsplit(1L)
