Re: sprintf: max number of characters printed?

Show all headers | View raw

OK,  replacing %s -> %120s (or %-120s) does not chop the command and prints it correctly, but it is still a mystery why %s prints the output as mentioned before since it does not chop the string corresponding to %s but the last characters of the resulting string.

do for [f in files]{ print sprintf("head %120s|awk '/srkappa/{printf \"(\%7.4f,\%7.4f)\",$4,$5}'",f)}
