Subject: [PATCH v9 13/15] syscalls: Avoid matching substrings in the ABI parsing
Date: Thu, 05 Nov 2026 17:05:48 -0300 [thread overview]
Message-ID: <20261105-tonyk-syscall_table-v9-13-8d1275885d9c@igalia.com> (raw)
In-Reply-To: <20261105-tonyk-syscall_table-v9-0-8d1275885d9c@igalia.com>
Currently, the abi parsing for grep will match substrings. For instance, an
ABI called `abc` will match also the ABI called `abcde`. Use the space
limiter to match a complete word and avoid matching substrings.
While here, add a true command in the end of grep command to avoid the
script exiting earlier and being able to do the cleanup.
