                                                                }

                                                                {
                                                                        o = o (a[i]"="(d[a[i]]?d[a[i]]:0)",")
                                                                }
                                                                        sub(",*$","",o)
                                                                        print o
                                                                }' /var/log/treg.test

Regards.

thank you so much!

this looks promising. when i run it though, it only gives a count for one of the strings even though there are lines in the data file that contain the other strings:

Code:

accepted=0,error=0,fail=3859,panic=0

        n++
        printf("%s=%s%s", i, a[i], (n < 4 ? ", " : "\n"))
    }
}' file

this looks quite promising as well. thank you so much!!!

looks like the code is written in such a way that it only counts the number of lines that contain just the specific patterns specified. but i believe i can play with it some more.

one question. is the "n < 4" setting a limit of patterns that can be specified?

btw, this completed in under .3 seconds on a 5mb file. so very good news!!!
