Count occurrences of character per line/field on Unix

Question

Given a file with data like this (ie stores.dat file)

sid|storeNo|latitude|longitude
2tt|1|-28.0372000t0|153.42921670
9|2t|-33tt.85t09t0000|15t1.03274200
         


        

Answer 1

awk '{gsub("[^t]",""); print length($0),NR;}' stores.dat

The call to gsub() deletes everything in the line that is not a t, then just print the length of what remains, and the current line number.

Want to do it just for column 2?

awk 'BEGIN{FS="|"} {gsub("[^t]","",$2); print NR,length($2);}' stores.dat
