我有包含
的text1.txt<this can be anything, any number of line - no hardcoded>
<this can be anything, any number of line - no hardcoded>
param1=<this can be any value - no hardcoded>
<this can be anything, any number of line - no hardcoded>
<this can be anything, any number of line - no hardcoded>
我想用 abc
取代这部分这可以是任何值 - 没有硬编码什么应该是正确的SED命令? 请注意,由于环境限制,我无法灵活地使用任何语言,如perl,python或ruby~,并且只能使用Unix命令。 并且没有硬编码,除了 param1
提前多多感谢!

您想要的调用是
sed -e 's/param1=.*/param1=abc/' text1.txt

听起来你想要像s/<.\+>$/<abc>/
:
$ cat test1.txt
<this can be anything, any number of line - no hardcoded>
<this can be anything, any number of line - no hardcoded>
param1=<this can be any value - no hardcoded>
<this can be anything, any number of line - no hardcoded>
<this can be anything, any number of line - no hardcoded>
$ sed 's/<.\+>$/<abc>/' test1.txt
<abc>
<abc>
param1=<abc>
<abc>
<abc>
