awk - I want to check the numbers in the 1st column is equal to 2nd column -


i want check numbers in 1st column equal 2nd column, , 1st column should starting abc , ending def , number between these should matching 2nd column.

can me here please.

my input:

abc12345def |12345 |23132331331|

abc95678def |45678 |23132331331|

abc87887def |86187 |23132331331|

abc89043def |89043 |23132331331|

output should be:

abc12345def |12345 |23132331331|

abc89043def |89043 |23132331331|

i'm trying use foollowing one, it's not working. awk -f '|' '($1 !~ /abc+[$2]+def/)' whtfile.txt > qc2valid.txt

this should work requirement:

awk -f'|' '{s=$2;sub(/\s/,"",s)}$1 ~ s' input abc12345def |12345 |23132331331| abc89043def |89043 |23132331331|

the problems in codes:

  • you cannot concatenate strings in awk +
  • you cannot concatenate strings in awk between /.../, static regex expression
  • you should use ~ instead of !~, requirement described.
  • your column 2 has empty strings, should remove them before matching
