刪除從匹配線到末尾的所有行，包括匹配線

這是我們要刪除包含“ EXPORTER_JAR_PATH”的行直到文件末尾的所有行的文件

EXPORTER_JAR_PATH 這是我的解決方案，從包含 -直到結束的行中刪除行

export EXPORTER_JAR_PATH=/tmp/hgt.yml

正如我們所看到的那一行——Export EXPORTER_JAR_PATH=/tmp/hgt.yml

依然存在，我們哪裡錯了？

sed '/EXPORTER_JAR_PATH/,$d' file

這將刪除從包含子字串的第一行EXPORTER_JAR_PATH到文件末尾（$地址文件末尾）的所有行。

指令的作用是刪除不在第 1 行和包含該字串的行（包括第 1 行）之間範圍內的所有行。這意味著包含子字串的行EXPORTER_JAR_PATH不會被刪除。

或者，正如 Paul_Pendant 和 mosvy 在下面的評論中指出的那樣，

sed -n '/EXPORTER_JAR_PATH/q;p' file

它將明確地p列印出每一行，直到到達EXPORTER_JAR_PATH腳本將終止的行。由於該-n選項禁用普通預設輸出，因此不會列印包含字串的行。這樣做的好處是sed不必讀取整個文件（但是，在這種特定情況下，由於文件太短，因此不會產生顯著差異）。

awk與等效的內容是：

awk '/EXPORTER_JAR_PATH/ { exit } { print }' file

或者，更短，

awk '/EXPORTER_JAR_PATH/ { exit }; 1' file
