test -O
is a bash/ksh/dash/ash extension to check
whether the file is owned by you.
To ensure compatibility with other shells, you can use
find -user "$(id -u)"
.
If you expect your shell to support test -O
, specify
this explicitly in the shebang (or with
# shellcheck shell=dash
directive).
ShellCheck is a static analysis tool for shell scripts. This page is part of its documentation.
