Using sed in shell script for replacing values in a file

Question

Please help me creating a shell script to search all lines and replace format in a file using sed.

Example - ['abc,xyz'] to be changed to ['abc','xyz']

Answer 1

Here you go:

[user@myserver ~]$ echo "['abc,xyz']" | sed "s:,:\',\':g"
['abc','xyz']

Here colon ( : ) is used as delimiter and backslash ( \\ ) has been used as escape character in sed command.

Answer 2

这可能对你有用（GNU sed）：

sed -E ':a;s/(\[('\''[^'\'',]*'\'',)*'\''[^'\'',]*),([^]]*'\''\])/\1'\'','\''\3/;ta' file
