ssam - stream interface to sam

SYNOPSIS

ssam [ -n ] [ -e script ] [ -f sfile ] [ file ... ]

DESCRIPTION

Ssam copies the named files (standard input default) to the standard output, edited by a script of sam commands (q.v.). When the script starts, the entire input is selected. The -f option causes the script to be taken from file sfile. If there is a -e option and no -f, the flag -e may be omitted. The -n option suppresses the default output.

ssam 'y/[a-zA-Z]+/ c/\n/' | grep . | sort | uniq -c
