How to check syslog in Bash on Linux?
By default it's logged into system log at /var/log/syslog, so it can be read by:
tail -f /var/log/syslogIf the file doesn't exist, check /etc/syslog.conf to see configuration file for syslogd.Note that the configuration file could be different, so check the running process if it's using different file:
# ps wuax | grep syslogroot /sbin/syslogd -f /etc/syslog-knoppix.confNote: In some distributions (such as Knoppix) all logged messages could be sent into different terminal (e.g. /dev/tty12), so to access e.g. tty12 try pressing Control+Alt+F12.
You can also use lsof tool to find out which log file the syslogd process is using, e.g.
sudo lsof -p $(pgrep syslog) | grep log$ To send the test message to syslogd in shell, you may try:
echo test | loggerFor troubleshooting use a trace tool (strace on Linux, dtruss on Unix), e.g.:
sudo strace -fp $(cat /var/run/syslogd.pid)
