The pager (and the attached terminal emulator) should be able to convert those codes (Escape, [, code sequence) into something meaningful, usually a change of display attributes such as color, inverse, underlined (or whatever the terminal supports). In your case, those are displayed as-is. Standard FreeBSD installations usually display them as desired: -setup_dirs() <--- red text +setup_dirs2() <--- green text Note that "ESC" is wrong (or probably just a display replacement for a non-printable character): The character has to be the ESC code (ASCII #27 or 0x1b), as seen here: 00000000 1b 5b 33 31 6d 2d 73 65 74 75 70 5f 64 69 72 73 |.[31m-setup_dirs| 00000010 28 29 1b 5b 6d 0a 1b 5b 33 32 6d 2b 1b 5b 6d 1b |().[m..[32m+.[m.| 00000020 5b 33 32 6d 73 65 74 75 70 5f 64 69 72 73 32 28 |[32msetup_dirs2(| 00000030 29 1b 5b 6d 0a |).[m.| Maybe your input data got mangled somehow and the ESC character replaced by the string "ESC", just as hexdump represents it as a "." in the ASCII output column? -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
