我正在嘗試更改連結的權限。我希望“其他”實體僅具有讀取權限,但是當我運行命令時,權限不會更改。是否有什麼我做得不正確,或者有不同的方法來更改連結的權限。
linux-gn77:~ # ls -l /usr/bin/startup.sh
lrwxrwxrwx 1 root dev 31 May 3 20:33 /usr/bin/startup.sh -> /usr/lib /tomcat7/bin/startup.sh
linux-gn77:~ # chmod 770 /usr/bin/startup.sh
linux-gn77:~ # ls -l /usr/bin/startup.sh
lrwxrwxrwx 1 root dev 31 May 3 20:33 /usr/bin/startup.sh -> /usr/lib/tomcat7/bin/startup.sh
linux-gn77:~ # chmod o=r /usr/bin/startup.sh
linux-gn77:~ # ls -l /usr/bin/startup.sh
lrwxrwxrwx 1 root dev 31 May 3 20:33 /usr/bin/startup.sh -> /usr/lib/tomcat7/bin/startup.sh
linux-gn77:~ # chmod o-r /usr/bin/startup.sh
linux-gn77:~ # ls -l /usr/bin/startup.sh
lrwxrwxrwx 1 root dev 31 May 3 20:33 /usr/bin/startup.sh -> /usr/lib/tomcat7/bin/startup.sh
請讓我知道如何實現這一目標。謝謝

您無法變更連結的權限。您將需要更改目標的權限。這記錄在man 2 symlink
:
The permissions of a symbolic link are irrelevant; the ownership is
ignored when following the link, but is checked when removal or renam‐
ing of the link is requested and the link is in a directory with the
sticky bit (S_ISVTX) set.
所以,為了實現你想要的,你需要運行
chmod 770 /usr/lib/tomcat7/bin/startup.sh
