Awk
awk 無需手動輸入
跑步是怎麼來
man awk
的No manual entry for awk
?坦率地說,我從來沒有在我的 Archlinux 系統上親自安裝過 Awk,但我剛剛發現在目前的,我最後安裝的,沒有man awk
,這很奇怪。man gawk
另一方面,工作正常。有什麼線索嗎?
這是版本以及其他可能相關的輸出:

從
man man
,手冊頁通常儲存在/usr/share/man
.由於 Awk 有幾個實現(
gawk
,mawk
, …),它通常是一個符號連結,指向要使用的真正 Awk,在你的情況下,是 GNU awk。它的聯機幫助頁也是如此:$ readlink /usr/share/man/man1/awk.1.gz /etc/alternatives/awk.1.gz $ readlink /etc/alternatives/awk.1.gz /usr/share/man/man1/gawk.1.gz
檢查您是否可以在
/usr/share/man
.find /usr/share/man/man1 -path '*/awk*'
- 如果是,它可能是一個損壞的連結,在這種情況下,您可以刪除它並創建一個指向所需手冊頁的連結(見下文)。
- 如果沒有,則連結失去。不知何故你刪除了它或它沒有發貨。這可能可以通過再次安裝軟體包來解決。否則,手動創建符號連結:
ln -s /usr/share/man/man1/gawk.1.gz /usr/share/man/man1/awk.1.gz
