Good morning, Few days ago, I noticed something strange with dash and IFS. It was verified with the following versions : - 0.5.10.2 on Voidlinux - 0.5.10.2 on Debian Buster - 0.5.8 on Ubuntu 18.04.2 LTS (Bionic Beaver) Here the issue : $ ls file.sign file1 file2 other.sign whileifs* $ cat whileifs #!/bin/dash find . -type f | sort -d | while IFS=$'\n' read -r F; do printf "%s\n" "$F" done $ ./whileifs ./file1 ./file2 ./file.sig ./other.sig ./whileifs file.sig and other.sig are returned instead of file.sign and other.sign. Here the result with bash : $ bash whileifs ./file1 ./file2 ./file.sign ./other.sign ./whileifs Here the result with mksh : $ mksh whileifs ./file1 ./file2 ./file.sign ./other.sign ./whileifs Here the result with lksh : $ lksh whileifs ./file1 ./file2 ./file.sign ./other.sign ./whileifs Here the result with busybox ash (1.31.0) : $ /tmp/busybox-x86_64 ash whileifs ./file1 ./file2 ./file.sign ./other.sign ./whileifs I attached the test directory. Can you reproduce it ? Sincerely Y
