Unix command to escape spaces

Question

I am new to shell script. Can someone help me with command to escape the space with \"\\ \". I have a variable FILE_PATH=/path/to my/text file ,
I want to escape the spa

Answer 1

FILE_PATH=/path/to my/text file
FILE_PATH=echo FILE_PATH | tr -s " " "\\ "

That second line needs to be

FILE_PATH=echo $FILE_PATH | tr -s " " "\\ "

but I don't think it matters. Once you have reached this stage, you are too late. The variable has been set, and either the spaces are escaped or the variable is incorrect.

FILE_PATH='/path/to my/text file'
