Awk is your friend :D
Awk script (snip.awk):

Code:
{
        for( i = 1; i <= NF; i++)
                if ( $i !~ /#34/ )       # your pattern goes here
                        printf "%s ", $i
        printf "\n"
}

Data file (myfile):

Code:
#34 * 2297 * 410 * 964 * * 4352
#44 * 244 * 43 * 4 4 4
#55 * #34 * * * * ddd * *

Output:

Code:
# awk -f snip.awk myfile
* 2297 * 410 * 964 * * 4352 
#44 * 244 * 43 * 4 4 4 
#55 * * * * * ddd * *

zfgrep

ZGREP(1)						    BSD General Commands Manual 						  ZGREP(1)

NAME

     zgrep, zegrep, zfgrep -- print lines matching a pattern in gzip-compressed files

SYNOPSIS

     zgrep [grep-flags] [--] pattern [files ...]

     zegrep [grep-flags] [--] pattern [file ...]

     zfgrep [grep-flags] [--] pattern [file ...]

DESCRIPTION

     zgrep runs grep(1) on files or stdin, if no files argument is given, after decompressing them with zcat(1).

     The grep-flags and pattern arguments are passed on to grep(1).  If an -e flag is found in the grep-flags, zgrep will not look for a pattern
     argument.

     zegrep calls egrep(1), while zfgrep calls fgrep(1).

EXIT STATUS

     In case of missing arguments or missing pattern, 1 will be returned, otherwise 0.

SEE ALSO

     egrep(1), fgrep(1), grep(1), gzip(1), zcat(1)
