log.sh is a Bash library for easy logging with preset configurations.
make install
You can also use PREFIX=$HOME to install log.sh to ~/bin, or any other location.
Please run the example.sh, the following screenshot was taken from the output of version 0.1.

# You are good to go
LSERROR Test error message
# or you can pipe the message
echo Test error message via pipe | LSERROR
LS_DEBUG_LEVEL=10
LS_INFO_LEVEL=20
LS_WARNING_LEVEL=30
LS_ERROR_LEVEL=40
LS_CRITICAL_LEVEL=50
The default logging level is LS_WARNING_LEVEL and the value is stored at LS_LEVEL. If you need debug or info message, set LS_LEVEL to them.
LSDEBUG
LSINFO
LSWARNING
LSERROR
LSCRITICAL
All arguments supplied to these function are treated as the message. There is also a general logging function LSLOG:
LSLOG 35 A message for level 35
The first parameter is the level. You do not need to use preset levels actually, as long as the level is equal to or greater than LS_LEVEL, the message will be printed out.
The default LS_OUTPUT is set to /dev/stdout, you can change it to /dev/stderr or any filename. Note that, it overwrites the file.
