Target

Implement recording of SHELL execution start time, end time, running status, error information, etc. Use the function to encapsulate log records and use scripts to call functions.

How does a shell Script Generate a running log?

The log printing function called by a self-written script for your reference.

Work starting with Script
Define Log File LOGFILE
Define log serial number file _ LOGSEQ

Define log Functions
Log ()
{
# Check whether a log file exists. If yes, check whether the file is too large (20 mb)
# If it is too large, switch the file and save the current log serial number in _ LOGSEQ.
If [-f $ LOGFILE]; then
LogFileLen = 'LS-l $ {LOGFILE} | awk '{print $5 }''
If [$ LogFileLen-gt 20971520]; then
If [-f $ {_ LOGSEQ}]; then
_ OrgSeq = "'cat $ {_ LOGSEQ }'"
If [$ _ OrgSeq-gt 98]; then
LogFileSeq = 0
Else
LogFileSeq = 'expr $ {_ OrgSeq} + 1'
Fi
Else
LogFileSeq = 0
Fi
Echo "$ {LogFileSeq}" >$ {_ LOGSEQ}
Mv $ LOGFILE $ {LOGFILE}. $ {LogFileSeq}
Fi
Fi
_ LogInfo = $1
Echo 'date + 20' % y-% m-% d % H: % M: % S' "$ {_ LogInfo}" >$ {LOGFILE} 2> & 1
}

Call the log function when logging is required.

Shell script to analyze log files

You just gave me a piece of your log. What to analyze.
