sed用文件夹中所有文件中包含破折号的字符串替换字符串

Question

In all files in a fodler, I am trying to replace all strings of the type:

load(alpha)

to

load(alpha, lib="lib=~/project-a/alpha")

using sed I tried:

find . -type f -print0 | xargs -0 sed -i 's/load(alpha)/load(alpha, lib="lib=~/project-a/alpha")/g'

But I get the error: sed: -e expression #1, char 39: unknown option to `s'

Any idea what I am missing? Thank you!

Answer 1

You get that error because the / delimiters with the substitute command are conflicting with the directory separators in your replacement; after the first directory separator is encountered, sed considers the replacement aborted. Change your delimiter to something else for a more clearer command.

sed -i 's!load(alpha)!load(alpha, lib="lib=~/project-a/alpha")!g'

Answer 2

find . -type f -print0 | xargs -0 sed -i 's/load(alpha)/load(alpha, lib="lib=~\/project-a\/alpha")/g'

In your command the character / is tehe delimiter, so you need to escape any forward-slashes that are part of your data as in /project-a/alpha -> \\/project-a\\/alpha

Alternatively you can a different delimiter (in this case the # character)

find . -type f -print0 | xargs -0 sed -i 's#load(alpha)#load(alpha, lib="lib=~/project-a/alpha")#g'
