I have this simple awk program but it not prints var_cab whe^E or ^S or ^M after he finds the second ^C

/^C/ { var_cab = substr($0,1,28); ent = 0 ; print "estoy en cabecera" var_cab;}
/^E/ { if ( ent ==0 ) var_fech = substr($0,4,8) ; ent ++;
print var_cab var_fech $0; }
/^S/ { print var_cab var_fech $0; }
/^M/ { print var_cab var_fech $0; }
END { print var_cab,ent}


the input file is many lines like this, every new block stats with ^CAB

Jozelo, please start your own thread. Don't hijack someone else's thread.

I am sorry...

I do not know how to start a thread...

No problem. If you can click on the "Forums" menu just below LQ logo. It will list all available sections of LQ. Click on the relevant one (probably Linux - Newbie would be best in this case) and click on "New Thread" button.
