# \[PATCH\] tracing/selftests: Fix false bashism in kprobe\_non\_uniq\_symbol.tc - From: Steven Rostedt \ - Date: 2026-10-30 01:12:23 - List: linux-trace-kernel - Page: https://ratatoskr.run/linux-trace-kernel/2026/10/17830153 - Thread: https://ratatoskr.run/linux-trace-kernel/2026/10/17830153/t.md ```text From: Steven Rostedt The checkbashism is giving a false positive to the kprobe test of: ($"foo" should be eval_gettext "foo"): if [ "$(grep -c -E "[[:alnum:]]+ t ${SYMBOL}$" /proc/kallsyms)" -le '1' ]; then This is because it sees the $" at the end of the grep as a bash symbol. Instead, escape the '$' with a backslash as it is within quotes and that '$' is for grep to process an end of line character and not a bash variable.
