Hi,
Writing TEXT processing script in BASH is just a quick job. For real
world needs, use AWK (See Karsten's answer to your post), PERL, or PYTHON.
Besides, Karsten's awk script addresses needs to keep them lower case
etc. IF you use BASH, you need to run 'tr' command externally. AWK,
PERL, and PYTHON script can be extended easily.
All said, BASH has parameter substitution command which addresses your
question.
READ the man page then see below. (Or grab one of those Oreilly books.)

echo
${n1:0:1}${n2}:${n1:0:2}${n2:0:2}:${pid}:${pid}:,,,/home/${n1:0:1}${n2}:/bin/bash
This makes even slightly customized password:-)
See use of ${parameter##word} ${parameter%%word} etc. for other
substitution.
