This still is far from clear. Is the line you cited not the command line? Please give way more context.

Just guessing: Do you want to read/assign something into a shell variable and use that instead of the show log, and it must be single quoted? Try double quoting the entire single quoted variable, as single quotes lose their meaning inside double quotes:
Code:
 CMD="list file"
echo '$CMD'
$CMD
echo "'$CMD'"
'list file'

TRACE-CMD-CHECK_EV(1)													     TRACE-CMD-CHECK_EV(1)

NAME
trace-cmd-check-events - parse the event formats on local system SYNOPSIS
trace-cmd check-events [OPTIONS] DESCRIPTION
The trace-cmd(1) check-events parses format strings for all the events on the local system. It returns whether all the format strings can be parsed correctly. It will load plugins unless specified otherwise. This is useful to check for any trace event format strings which may contain some internal kernel function references which cannot be decoded outside of the kernel. This may mean that either the unparsed format strings of the trace events need to be changed or that a plugin needs to be created to parse them. OPTIONS
-N - Don't load plugins SEE ALSO
trace-cmd(1), trace-cmd-record(1), trace-cmd-report(1), trace-cmd-stop(1), trace-cmd-extract(1), trace-cmd-reset(1), trace-cmd-split(1), trace-cmd-list(1), trace-cmd-listen(1), trace-cmd-start(1) AUTHOR
