尝试使用 sed 命令将此 var 包含在 test.txt 文件中以删除双引号

Question

I'm attempting to include this var in the test.txt file using sed command.

Tried below script:

#!/bin/bash
var="test 'test:test:1.0'"
sudo sed -i '/dependencies {/a '"${var}"'' test.txt

test.txt

  dependencies {        
        implementation 'org.springframework.boot:spring-boot-starter-web'
        implementation 'org.springframework.boot:spring-boot-starter-cache'        
    }
}

group = 'org.gradle'

I'm using sed to do it, and it's updating the test.txt file, but it's adding with double quotes,

Current script result:

dependencies {
"test 'test:test:1.0'"
implementation 'org.springframework.boot:spring-boot-starter-web'
implementation 'org.springframework.boot:spring-boot-starter-cache'        
    }
}

group = 'org.gradle'

and if i remove the double quotes from the variable or sed command results in an error.

Error

sed: can't read 'ch.qos.logback:logback-classic:1.2.2'": No such file or directory

How can I ignore this double quotes?

Answer 1

If I use OP's var assignment ...

var="test 'test:test:1.0'"

... then OP's sed generates:

  dependencies {
test 'test:test:1.0'
        implementation 'org.springframework.boot:spring-boot-starter-web'
        implementation 'org.springframework.boot:spring-boot-starter-cache'
    }
}

In other words, I'm unable to reproduce the issue.

On the other hand if, as KamilCuk's surmised, var contains double quotes, eg:

var="\"test 'test:test:1.0'\""

... then I can duplicate OP's output.

So, assuming the double quotes are actually part of what's assigned to var , one idea is to use paramater substitution, eg:

var="\"test 'test:test:1.0'\""
sed "/dependencies {/a ${var//\"/}" test.txt

NOTE: once OP is satisfied with the results the -i flag can be added back into the sed call

This generates:

  dependencies {
test 'test:test:1.0'
        implementation 'org.springframework.boot:spring-boot-starter-web'
        implementation 'org.springframework.boot:spring-boot-starter-cache'
    }
}
