Similar to what has been posted so far but allowing to count occurrences of undesired characters:
Code:
awk '
        {TMP = substr ($0, 7, 1)
         if (TMP ~ "[" SRCH "]") C[TMP"_hosts"]++
         else                    C["None   "]++
        }
END     {for (c in C) print c, "=", C[c]
        }
' SRCH="pdo" file

d_hosts = 1
None    = 8
p_hosts = 17
o_hosts = 1

SHTOOL-FIXPERM.TMP(1)					      GNU Portable Shell Tool					     SHTOOL-FIXPERM.TMP(1)

NAME
shtool-fixperm - GNU shtool file permission fixing command SYNOPSIS
shtool fixperm [-v|--verbose] [-t|--trace] path [path ...] DESCRIPTION
shtool fixperm fixes file permissions inside a source tree under path by cleaning up the permission bits. It determines the cleaned up permission from the already set bits. It is intended to be run before a tarball is rolled (usually with shtool tarball) out of a source tree. The trick is that this is more convenient than having to set the permissions manually or by using a large file list. OPTIONS
The following command line options are available. -v, --verbose Display some processing information. -t, --trace Enable the output of the essential shell commands which are executed. EXAMPLE
# Makefile.in dist: shtool fixperm -v * ... HISTORY
The GNU shtool fixperm command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 1996 for OSSP eperl. It was later taken over into GNU shtool. SEE ALSO
shtool(1), chmod(1). 18-Jul-2008 shtool 2.0.8 SHTOOL-FIXPERM.TMP(1)
