I am also having this bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=879555
$ parted -v parted (GNU parted) 3.6 Copyright (C) 2023 Free Software Foundation, Inc. License GPLv3+ Written by <http://git.debian.org/?p=parted/parted.git;a=blob_plain;f=AUTHORS>. $ cat /etc/lsb-release DISTRIB_ID="ManjaroLinux" DISTRIB_RELEASE="24.0.2" DISTRIB_CODENAME="Wynsdey" -- If increasing the size of a partition the following command works but if reducing the size of a partition it gives a warning "Warning: Shrinking a partition can cause data loss, are you sure you want to continue?" and the command just exits back to the command prompt and no changes are made to the partition. sudo parted -s /dev/loop0 resizepart 1 46280703s I assumed that parted -s would automatically supply a default value of 'Yes' in this instance? According to the Parted Man page: -s, --script never prompts for user intervention Is this a bug or am I misunderstanding something? >From researching the interweb this might be a bug that for many years has never been addressed. There appears to be no way to make this work with parted -s. The only option is to resort to the undocumented ---pretend-input-tty <-- But is this safe to keep using if not documented? Any plans to make it an official "thing" in Parted? Example that will work whether increasing or reducing the partition size: echo -e "resizepart 1 46280703s\nyes\nunit s\nprint\nquit" | sudo parted /dev/loop0 ---pretend-input-tty Any help much appreciated, Flex
