Answer 1

egrepエスケープ|も必要な代替をサポートします。[

egrep "^\[(bugID|TICKET-)[[:digit:]]{1,}\]" file
[bugID12345] fix for performance issue
[TICKET-12345] fix for memory leak issue
[bugID23244] fix for performance issue
[TICKET-54678] fix for memory leak issue

行全体が必要ない場合は、次の-oオプションを使用します。

egrep -o "^\[(bugID|TICKET-)[[:digit:]]{1,}\]" file
[bugID12345]
[TICKET-12345]
[bugID23244]
[TICKET-54678]
