Having nothing on stdout when executing awk script












0















I run a awk script. But, it is here. This is the command awk -f awk_scr ERR.txt.



BEGIN {

FS=" " 

target="missing" 

}

{

for (i=1; i <= NR; i++) {

  for(j=1; j <= NF; j++) {

    if ($j == target) {

      do { 

        printf $j > "final.txt" 

      } while (j == NF)

    }           

    if (j == NF) {

      printf "n"

    }

  }

}

}


The ERR.txt content is here. This awk script is for trimming what that is matched by "missing" and then print to a file, final.txt.

shell-script awk

  • Please clarify what you mean by "trimming". Note that the code block that you have in your awk script will be executed once for each line in the input. Having a loop over NR is therefore not needed, unless you'd like to do the inner loop once for the first line, twice for the second line, thrice for the third, etc.

Accessing regular linux commands in Huawei's Dopra Linux

Image
4 Backstory: I have a Huawei HG8245 router in my house and I want to change the default username/password. I've tried following this guide but the config file always gets reset. My ISP isn't helping either so I'm looking for other ways to accomplish this. The router has telnet access so this seems like a way to change the credentials. The first shell I gain access to looks like this: WAP> Pressing "?" gives me a list of available commands which I've pasted here, the two interesting ones are "su" and "shell".
