getting basename inside awk script

Shell Programming and Scripting
1

hi if we have to use basename how can we do this in awk?
did the below but is not working..

 
psg  -t  "?"|  awk '{
                        command=($5 ~ /^[A-Z]/)? $9:$8
                       #  cmd_name=`basename $command` (gives error)
                        system("basename $command >> cmd_name") (isnot working )
                        }'

thanks

Something like this ?..

 
psg  -t  "?"|  awk '{
                        command=($5 ~ /^[A-Z]/)? $9:$8
                        exe="basename " cmd_name " >>" cmd_name
                        system(exe)                         
                       }'

psg  -t "?"| awk  '{
             command=($5 ~ /^[A-Z]/)? $9:$8
             exe="basename " command " >> command"
             system(exe)
             printf(" second name %s \n",command)
             }'

its not printing the basename!!

Check in the current directory( where you executed the script) , a file with name "command" . The content of the file will be basename's output.

How ever if you want the system output to be seen on screen then make the following change in your script:

exe="basename " command 
          system(exe)

I want to use the command variable like this than what i have to do??

 
psg  -t "?"| awk  '{
             command=($5 ~ /^[A-Z]/)? $9:$8
             exe="basename " command " >> command"
             system(exe)
             if (command == "tec")
             {
             printf(" second name %s \n",command)
             }
             }'

You can use ..the same working fine for me.

print "command" value and check wat ur getting ?..

I did n't understand the logic behind your script.

If you post input and output your expecting , then i hope you can get

more responces.

once again - why do you need to invoke an external command when you can do it all within awk natively?

psg  -t "?"| awk  '{
             command=($5 ~ /^[A-Z]/)? $9:$8
             exe="basename " command " >> cmd_Name"
             system(exe)
              if (cmd_Name == "tec")
              {
                kill=1
              }
              if (kill ==1)
              {
              op=kill -9 " pid ";
              system(op)
              }
             }'

I want get the name of the process and compare to check if it is "tec" process or not if it is ,then i would kill it.

how can we do it?
by doing natively do you mean to say using reg expression.?

one way......

myPathname="/a/b/c/d/myExec"
n=split(myPathname, a, "/")
print a[n]

one more way..

 
              psg  -t "?"|  awk '{
              cname=($5 ~ /^[A-Z]/)? $9:$8
              len=length(cname)
              regex="/"
              for(i=1;i<=len;i++)
              {
                  where = index(cname,regex)
                  if(where)
                  {
                       cname= substr(cname,where+1)
                  }
              }
              printf("%s \n",cname)
          }'
