When a tcsh script has DOS line endings and a line ending falls in bytes 32767 and 32768, the line ending is lost. I discovered this with a scriptpassing shell input to a program using the << construct, and have reproduced the problem with a script (bigscript) that passes 4 lines of input to another script. The functional part of the script is
./testreader <<EOF key1 value1 key2 value2 key3 value3 key4 value4 EOF
and the rest is filler to bring the line ending between the second and third line to the 32768 byte boundary. testreader simply reads and echos four lines of input. Here is the result of running bigscript - it passes both lines to the reader: [m...@salsa ~]$ ./bigscript Line 1: key1 value1 Line 2: key2 value2key3 value3 Line 3: key4 value4Line 4: [m...@salsa ~]$ od -c bigscript | grep -B 1 0100000
0077760 \r \n k e y 2 v a l u e 2 \r 0100000 \n k e y 3 v a l u e 3 \r \n Here the script was modified to have one less character and it runs fine: [m...@salsa ~]$ ./bigscript2 Line 1: key1 value1 Line 2: key2 value2 Line 3: key3 value3 Line 4: key4 value4 [m...@salsa ~]$ od -c bigscript2 | grep -B 1 0100000 0077760 \n k e y 2 v a l u e 2 \r \n 0100000 k e y 3 v a l u e 3 \r \n k Here it was modified to have one more character and it runs fine: [m...@salsa ~]$ ./bigscript3 Line 1: key1 value1 Line 2: key2 value2 Line 3: key3 value3 Line 4: key4 value4 [m...@salsa ~]$ od -c bigscript3 | grep -B 1 0100000 0077760 1 \r \n k e y 2 v a l u e 2 0100000 \r \n k e y 3 v a l u e 3 \rConverting a script to unix line endings avoids the problem, even if a critical line ending is moved to byte 32767 or 32768.
The problem occurs on a cygwin installation with binmode mounts and not on one with textmode mounts.
