Нет, не глючит.

Можно собрать бинарник хоть под Linux, хоть под Windows:)
Ну, или man sed.
]]>Не совсем сформулировал задачу, нужно в готовый текст в начало строк нумерация, но наверное это сложнее
нет, не сложно, вот на примере готового файла hosts.allow
root@monitoring:/etc# cat hosts.allow
# /etc/hosts.allow: list of hosts that are allowed to access the system.
# See the manual pages hosts_access(5) and hosts_options(5).
#
# Example: ALL: LOCAL @some_netgroup
# ALL: .foobar.edu EXCEPT terminalserver.foobar.edu
#
# If you're going to protect the portmapper use the name "portmap" for the
# daemon name. Remember that you can only use the keyword "ALL" and IP
# addresses (NOT host or domain names) for the portmapper, as well as for
# rpc.mountd (the NFS mount daemon). See portmap(8) and rpc.mountd(8)
# for further information.
теперь номеруем строчки
root@monitoring:/etc# cat hosts.allow | cat -n
1 # /etc/hosts.allow: list of hosts that are allowed to access the system.
2 # See the manual pages hosts_access(5) and hosts_options(5).
3 #
4 # Example: ALL: LOCAL @some_netgroup
5 # ALL: .foobar.edu EXCEPT terminalserver.foobar.edu
6 #
7 # If you're going to protect the portmapper use the name "portmap" for the
8 # daemon name. Remember that you can only use the keyword "ALL" and IP
9 # addresses (NOT host or domain names) for the portmapper, as well as for

11 # for further information.
как видно, все пронумеровалось. но есть и второй способ. открой любой vi-подобный редактор. Например vim и напиши : set number. результат тот же самый увидешь. пример
1 # /etc/hosts.allow: list of hosts that are allowed to access the system.
2 # See the manual pages hosts_access(5) and hosts_options(5).
3 #
4 # Example: ALL: LOCAL @some_netgroup
5 # ALL: .foobar.edu EXCEPT terminalserver.foobar.edu
6 #
7 # If you're going to protect the portmapper use the name "portmap" for the
8 # daemon name. Remember that you can only use the keyword "ALL" and IP
9 # addresses (NOT host or domain names) for the portmapper, as well as for
10 # rpc.mountd (the NFS mount daemon). See portmap(8) and rpc.mountd(8)
