I set variables in a loop that's in a pipeline. Why do they disappear after the loop terminates? Or, why can't I pipe data to read? In most shells, each command of a pipeline is executed in a separate SubShell. Non-working example: # Works only in ksh88/ksh93, or zsh or bash 4.2 with lastpipe enabled # In other shells, this will print 0 linecount=0 printf '%s\n' foo bar | while IFS= read -r lined
