How to input a path with a white space?

问题:

I have a main file which uses(from the main I do a source) a properties file with variables pointing to paths.

The properties file looks like this:

TMP_PATH=/$COMPANY/someProject/tmp
OUTPUT_PATH=/$COMPANY/someProject/output
SOME_PATH=/$COMPANY/someProject/some path

The problem is SOME_PATH, I must use a path with spaces (I can't change it).

I tried escaping the whitespace, with quotes, but no solution so far.

I edited the paths, the problem with single quotes is I'm using another variable $COMPANY in the path

回答1:

Use one of these threee variants:

SOME_PATH="/mnt/someProject/some path"
SOME_PATH='/mnt/someProject/some path'
SOME_PATH=/mnt/someProject/some\ path

I see Federico you've found solution by yourself. The problem was in two places. Assignations need proper quoting, in your case

SOME_PATH="/$COMPANY/someProject/some path"

is one of possible solutions.

But in shell those quotes are not stored in a memory, so when you want to use this variable, you need to quote it again, for example:

NEW_VAR="$SOME_PATH"

because if not, space will be expanded to command level, like this:

NEW_VAR=/YourCompany/someProject/some path

which is not what you want.

You can escape the "space" char by putting a \ right before it.

回答4:

SOME_PATH=/mnt/someProject/some\ path

should work

回答5:

If the file contains only parameter assignments, you can use the following loop in place of sourcing it:

# Instead of source file.txt
while IFS="=" read name value; do
    declare "$name=$value"
done < file.txt

This saves you having to quote anything in the file, and is also more secure, as you don't risk executing arbitrary code from file.txt.

If the path in Ubuntu is "/home/ec2-user/Name of Directory", then do this:

1) Java's build.properties file:

build_path='/home/ec2-user/Name\\ of\\ Directory'

Where ~/ is equal to /home/ec2-user

2) Jenkinsfile:

build_path=buildprops['build_path']
echo "Build path= ${build_path}"
sh "cd ${build_path}"
