How to search for file using regex

saurabh96

 Hello guys,

i have a  log file abc_rule321.log in PWD.

Now i want that if there isn't any log file in pwd it should print message-

if(isFileName("abc_rule*")== nil then       ;;;;;;;;;;;;;;;;;   am using * because it can be any number after abc_rule

fprintf(errport "Runs Not Started!...\n" )

Am not able to get output as it is not considering * regex extension ..it simply searching for abc_rule*.

i tried one way more-

if(system(ls abc_rule*) ==nil  then

fprintf(errport "Runs Not Started!...\n" )

how to correct and get above o/p

regards,

Parents

  • Neither of those will work, because:

    1. isFileName doesn't accept wildcards (not sure why you would think it does, since the documentation doesn't mention it
    2. The argument to system() is not in quotes
    3. system() returns the exit status of the command, not the output

    You could just use:

    pcreMatchList("^abc_rule" getDirFiles("."))

    as the condition. This returns a list (i.e. non-nil) containing any file that begins with abc_rule, so you can do:

    unless(pcreMatchList("^abc_rule" getDirFiles("."))
      fprintf(report "Runs not started\n')
    )
