bash : grep gives “No such file or directory” while searching for text in log

Question

in bash script i have these relative lines:

find_time(){ 
    args=( -A2 'Finished import for test' /var/apps/log/app.log )
     
    while    [ -z "$per_time" ] && [ $COUNTER -lt 3   ] ; do
        if grep -q "${args[@]}" ; then
            per_time=$(grep "${args[@]}" | grep Time) 
            output_time 
        elif ssh user@hostname grep -q -A2 'Finished import for test' /var/apps/log/app.log ; then
            per_time=$(ssh user@hostname 'grep -s -A2 "Finished import for test" /var/apps/log/app.log | grep "Time"') 
            output_time 
        else 
            sleep 60
        fi;  
     COUNTER=$((COUNTER+1))
    done 
    echo "find_time OK"
}
 
output_time () {
    time=${perf_time//[!0-9]/}
    #convert to seconds and round the value
    time=$(echo $time | sed 's/^\(.\{2\}\)/\1./' | awk '{ printf "%.1f\n",$1}')     
    echo -e "kpi5 : "$time" sec " >> "$result_file"
}

find_time

it gives me right result, however it shows in shell:

grep: import: No such file or directory
grep: for: No such file or directory
grep: test: No such file or directory

can not find out how to solve it.

You should put the whole command inside single quotes. So, I think you can try this one:

$(ssh user@host 'grep -A2 "Finished import for test " /var/apps/log/app.log | grep "Time"')
