"sed" o "awk" lanciato sulla finestra di apertura del terminale

A un certo punto, ho notato uno strano comportamento dell'app Terminal - ora all'apertura di una nuova finestra ottengo questo come normale:

ma dopo non è possibile vedere il segno "~" e il titolo della finestra mostra "Terminal - sed - 80x24" che significa che sed è in esecuzione. Dopo aver premuto due volte il tasto "invio", tutto diventa normale, ma ora dopo ogni nuovo comando inserito, devo premere due volte "Invio" dopo di esso. Questo mi fa impazzire! Non ho idea di cosa sia successo. Forse c'è uno script di configurazione di avvio per terminale / bash? Ho controllato .bash_profile sembra buono come prima.

Ecco il mio file .bash_profile:

alias twrangler="open -a TextWrangler"
alias countloc="find -f . '(' -name '*.m' -or -name '*.mm' ')' -print | xargs wc -l"

bind "set bell-style none" # No bell, because it's damn annoying
bind "set show-all-if-ambiguous On" # this allows you to automatically show completion without double tab-ing
