Linux上的Sed命令僅匹配1，在Solaris上找到多個匹配項

Question

注意我是SED的初學者。

我們使用sed-command查看clearcase命令的輸出，並獲取具有視圖的用戶的名稱：

<clearcase output> | sed -n "/Development streams:/,// s/[^ ]* *Views: *\([^_ ]*\)_.*/\1/p"

（示例clearcase輸出：

Project:              project:xx0.0_xx0000@/xxxx/xxxxx_xxxxxxxx0
Project's mastership: XXXXXXXXX@/xxxx/xxxxx_xxxxxxxx0
Project folder:       folder:XX0.0@/xxxx/xxxxx_xxxxxxxx0 (RootFolder/Xxxxxxxx/XX0.0)
Modifiable components:component:00000000000@/xxxx/xxxxxx_xxxxxxxx0
                      component:xxxxxxx_xxxxxxx@/xxxx/xxxxxx_xxxxxxxx0
                      component:xxxxxxxxxxxxxx_x@/xxxx/xxxxxx_xxxxxxxx0
                      component:xxxxx@/xxxx/xxxxxx_xxxxxxxx0
                      component:xxxxxx_xxxxxxxxxxx@/xxxx/xxxxxx_xxxxxxxx0

Integration stream:   stream:xx0.0_xx0000_integration@/xxxx/xxxxx_xxxxxxxx0 (FI: nemelis)
Integration views:    olduser_xx0.0_xx0000_int - Properties: dynamic ucmview readwrite nshareable_dos
                      nemelis_xx0.0_xx0000_int - Properties: dynamic ucmview readwrite nshareable_dos
                      otheruser_xx0.0_xx0000_int - Properties: dynamic ucmview readwrite nshareable_dos

Development streams:  stream:nemelis_xx0.0_xx0000@/xxxx/xxxxx_xxxxxxxx0 [unlocked] - No rebase or delivery is pending.
                       Views:nemelis_xx0.0_xx0000
                      stream:otheruser_xx0.0_xx0000_streamidentifier@/xxxx/xxxxx_xxxxxxxx0 [unlocked] - No rebase or delivery is pending.
                       Views:otheruser_xx0.0_xx0000_streamidentifier

）

在Solaris上它將輸出：

nemelis

otheruser

但是在（Redhat-）Linux上只給出了第一個名字。

（注意：我查看了Stackoverflow並發現了在Posix / Gnu上總是貪婪的注釋並且應該使用Perl（請參閱sed中的非貪婪正則表達式匹配？ ）。因此我嘗試用Perl修復它，但是比起我最后遇到問題，使用“//”，“|”，在<token>之前缺少運算符，等等，因此我的帖子在這里）

Answer 1

通過將地址指定為//不確定您要實現的目標。 您可能暗示它應該是文件結尾或空白行。 在前一種情況下使用$作為地址，在后一種情況下使用/^$/ 。

以下可能適合您：

sed -n "/Development streams:/,$ s/[^ ]* *Views: *\([^_ ]*\)_.*/\1/p"

從手冊：

$

  This address matches the last line of the last file of input, or the last line of each file when the `-i' or `-s' options are specified.
