Substitute “[“ to [ using sed

Question

I’m trying to correct some errors of a file with the following input:

"[""test""]"

And I want to get this output:

["teste"]

I already tried the following commands:

sed -i s/"["/[/g *.csv
sed -i s/"]"/]/g *.csv

I get this error message:

sed: -e expressou-me #1, character 7: Command `s' umfinished (s/// - mísseis delimitator)

Can someone please help me?

You have to escape [ as it stands for the bracket expression opening in POSIX BRE. The closing bracket ] can be left unescaped if it appears first (see point 1 in the standard quoted above).

sed -i 's/"\["/[/g; s/"]"/]/g' file

I had the same input – Jojo Oct 26 '17 at 12:43
What do you mean by that, I don't understand. This `sed` expression is *not* the same as yours (notice `\[`). – randomir Oct 26 '17 at 12:45
Can you try this on your example: `echo '"[""test""]"' | sed 's/"\["/[/g; s/"]"/]/g'`? – randomir Oct 26 '17 at 12:50
i cant use the ' because i'm in windows, but i tested with out it and the result is the same... – Jojo Oct 26 '17 at 13:55

You can try this one

sed 's/"//g;s/[a-z]\{1,\}/\"&e"/'
