colortail is not a full replacement for tail - namely, it precludes pipe/|/stdin
systemd-journalctl -f gives a non colorized output. Here's my failed attempt to fool colortail into accepting a bash file descriptor in order to pipe journal through colortail: Refer: http://www.tldp.org/LDP/abs/html/io-redirection.html $ cd /tmp $ sudo tail /var/log/syslog > t.txt $ ll t.txt 4.0K -rw------- 1 1.4K 2012-11-24 18:45 t.txt # Assign file descriptor 3 to t.xt: $ exec 3<> t.txt # attempts to use this to trick colortail command: $ colortail -f 3 colortail: Failed to open file: 3 # fail $ colortail -f &3 [1] 27522 bash: 3: command not found # fail; whoops, of course, & backgrounds prior command, so cleanup: $ jobs [1]+ Running colortail -f & $ fg colortail -f ^C$ jobs $ $ colortail -f "&3" colortail: Failed to open file: &3 ==> &3 <== #fail $ colortail -f '&3' colortail: Failed to open file: &3 ==> &3 <== #fail # Tried all options I could think of, so give up and cleanup FD3: $ exec 3>&- ======================== SO, it comes to my mind, that there ought be a way to turn a bash file descriptor, into a file name, to fool colortail in some other way. Perhaps a /proc/$PID/fd/... or some such. So: $ find /proc/|grep -i fd # gives lots and lots of output that looks promising $ sudo find /proc/|grep -i fd > t1 $ exec 3<> t.txt $ sudo find /proc/|grep -i fd > t2 $ diff t1 t2 # this gives waay too much output Anyone know where to next, in the search for ultimate control over colortail, taming it into submission to the will of systemd-journald? tia zenaan PS In addition to above, is there some other way to colorize journald's output? -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
