$ cat myf.txt
A|xyz|1000|mm
B|9000|xyz|ss
C|BDE|2000|kk
D|xyz|1000|nn

I am searching "xyz"

$ awk -F "|" '
{for(k=0;k<=NF;k++)
if ( $k == "xyz" )
print "line="NR"(column="k")"
}' myf.txt

Output:
line=1(column=2)
line=2(column=3)
line=4(column=2)


I want to see the output as :

line=1(column=2)
line=2(column=3)
line=3(Not found)
line=4(column=2)

awk -F "|" '
{found=0}
{for(k=0;k<=NF;k++)
   if( $k == "xyz" ){
     print "line="NR"(column="k")"
     found=1
   }
}
!found{print "line="NR" (not found)"}
' myf

> cat file
A|xyz|1000|mm
