Thank You Ravinder, Junior-Helper

cat myLogfile[12].log > mySingleLogfile.log solution suits my requirements.

In my case, the logfile names are assigned to variables first
Code:
[root@tblmanh236 test]# export LOG1=myLogfile1.log
[root@tblmanh236 test]# export LOG2=myLogfile2.log
[root@tblmanh236 test]# export LOG3=myLogfile3.log

And the below works well



Code:



[root@tblmanh236 test]# cat $LOG1 $LOG2 $LOG3 > mySingleLogfile.log
[root@tblmanh236 test]#

But, When I am trying to do the equivalent of myLogfile[12].log > mySingleLogfile.log with variables, I am getting the following error because of the [ ] brackets around 123 , I guess

Code:
[root@tblmanh236 test]# cat $LOG[123] > mySingleLogfile.log
cat: [123]: No such file or directory
[root@tblmanh236 test]#
[root@tblmanh236 test]# cat '$LOG[123]' > mySingleLogfile.log
cat: $LOG[123]: No such file or directory
[root@tblmanh236 test]#
[root@tblmanh236 test]#
[root@tblmanh236 test]# cat "$LOG[123]" > mySingleLogfile.log
cat: [123]: No such file or directory
[root@tblmanh236 test]#

## Escaping the brackets didn't work either
[root@tblmanh236 test]# cat $LOG\[123\] > mySingleLogfile.log
cat: [123]: No such file or directory

How can I get this working ?

logcheck-test

logcheck-test(1)					      General Commands Manual						  logcheck-test(1)

NAME

       logcheck-test - test new logcheck rules easily

SYNOPSIS

       logcheck-test [-q|-i] [-a|-s|-l FILE] [-e] [-P PREFIX] [-S SUFFIX] RULE
       logcheck-test [-q|-i] [-a|-s|-l FILE] -r RULEFILE

DESCRIPTION

       logcheck-test  parses  a log file for matching lines specified by a single rule or a rule file. If using a single RULE you can set a PREFIX
       and a SUFFIX to write new rules easily.

OPTIONS

       -h, --help
	      Show usage information

       -a, --auth.log
	      Parse /var/log/auth.log for matching lines

       -s, --syslog
	      Parse /var/log/syslog for matching lines

       -l, --log-file FILE
	      Parse FILE for matching lines

       -i, --invert-match
	      Show line that don't match the RULE or the RULEFILE

       -q, --quiet
	      Suppress rule summary at the end of output

       -e, --surround-rule
	      Surround RULE with standard prefix and suffix:

	      ^[[:alpha:]]{3} [ :[:digit:]]{11} [._[:alnum:]-]+ RULE$

       -P, --append-prefix PREFIX
	      Append PREFIX to rule prefix. Option can be given multiple times

       -S, --prepend-suffix SUFFIX
	      Prepend SUFFIX to rule suffix. Option can be given multiple times

       -r, --rule-file RULEFILE
	      Use file RULEFILE for rule input

EXAMPLES

       With logcheck-test you can easily write and test new rules.

       Test a single rule against /var/log/syslog:
	      logcheck-test -s "RULE"

       Test a single rule against ~/log, surround the rule with standard prefix and suffix and append "kernel " to prefix:
	      logcheck-test -l ~/log -e -P "kernel " "RULE"

       Test the rules in rulefiles/linux/ignore.d.server/kernel against ~/log:
	      logcheck-test -l ~/log -r rulefiles/linux/ignore.d.server/kernel

       Test which lines the rules in rulefiles/linux/ignore.d.server/kernel doesn't match:
	      logcheck-test -l ~/log -r rulefiles/linux/ignore.d.server/kernel -i

EXIT STATUS

       On successful matching logcheck-test will complete with exit code 0. An exit code of 1 indicates no successful matching.

       An exit code greater then 1 indicates an error occurred. Textual errors are written to the standard error stream.
