I was jus writin some perl scripts in linux and in the konsole I accidently type the double-qoute character ". bash ignored my whole command and dropped me into some kind of program or an alternate shell which is prompted by the forward arrow >, just like telnet or ftp. In here I can't make any commands or execute any programs and anything I enter it just displays another > prompt. I exited out of it with Ctrl-C so I know it's some kind of program, I just never heard about it and I can't find any info. I'm wonderin if anybody knows the purpose of " on the command line.
