And to complement/complicate that: $ file /usr/bin/firefox /usr/bin/firefox: symbolic link to `../lib/iceweasel/iceweasel' $ file /usr/bin/iceweasel /usr/bin/iceweasel: symbolic link to `../lib/iceweasel/iceweasel' $ file /usr/lib/iceweasel/iceweasel /usr/lib/iceweasel/iceweasel: POSIX shell script text executable If you examine it carefully, you'll notice it will eventually run: $ file /usr/lib/iceweasel/firefox-bin /usr/lib/iceweasel/firefox-bin: symbolic link to `../xulrunner-1.9/xulrunner-stub' $ file /usr/lib/xulrunner-1.9/xulrunner-stub /usr/lib/xulrunner-1.9/xulrunner-stub: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.8, stripped -- Tzafrir Cohen | [EMAIL PROTECTED] | VIM is http://tzafrir.org.il | | a Mutt's [EMAIL PROTECTED] | | best ICQ# 16849754 | | friend -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
