我想以包含每一种可能特性的体格取代%foo%
(见档案测试)。 由于缺少身份限制,以下因素是不可能的(在讲卫生运动第4节中执行):
echo %foo% > test
replacement="//this//is//a//test"
ed -s test <<< "g/%foo%/s/%foo%/$replacement"
如何用每一种可能的案文取代<代码>%foo%?

有了<条码>r条码>,就可以将案文从另一个档案中装载,因此以下是有效的解决办法:
r FILE
我恳请各位猜想,你会以每颗预估的反弹和反弹,接近你的目标。 AFAIK在单一步骤中无法做,因此,你可以书写功能,使之可以读懂,或者享受到你对红树林的访问:
$ echo %foo% > test
$ replacement="//this//is//a\\//test"
$ echo $replacement
//this//is//a\//test
$ stage1=${replacement//\/\\}
$ echo $stage1
//this//is//a\\//test
$ stage2=${stage1////\/}
$ echo $stage2
//this//is//a\\//test
$ ed -s test <<< g/.*foo.*/s/foo/$stage2/p
%//this//is//a\//test%
新的路线仍然是一个问题,但你不想让它们留在沥滤环境中,因为白天会在那里非常稳定。
