Root@ bin # more check_log.sh # check the error log scripts in all specified log files in a directory
#! / usr/bin/env bash # is a declaration of shell
Base= "/ home/project" # defines a variable that specifies the directory where the log is scanned
While [[1]]; definition of infinite loop in do # shell
For name in `ls $base | grep-vE "default" `; # the for loop begins to traverse the files in the directory and filter out the default directory
Do # starts execution
Echo $base/$name # output directory path
If [[- d $base/$name]]; then # determines whether it is a directory or not
Result= `grep-C10 $base/$name/logs/catalina.out | grep-vE "DEBUG | skywalking | 10.8.0.37 grep 8800" | grep-C5-E "Exception | ERROR" `
# get the log of Exception | ERROR reported in the catalina.out file, and filter out the DEBUG | skywalking | 10.8.0.37 ERROR 8800
If [[- z "$result"]]; then # if determines if $result is empty
Continue; # continue
Fi # if Terminator
Echo-e "\ n\ 033 [31mfind Exception in $name\ 033 [0m\ n\ nExcpetion:\ n\ n$result" # A line of colored output indicates which directory has reported an error
Fi # if Terminator
Done # do Terminator
Echo-e "sleep 60 seconds\ n" # output take a minute break
Sleep 60s # wait one minute
Done # do Terminator
