[SOLVED] Bash: save multiline text with variable in file

Ambalo · 03-20-2016, 11:55 AM

Hi,

i wanna save multiline text with variable in a file.

The following shows a example:

Code:

${text} = ${Array[i]}

${text[$p - $v]} =  ${Array[i]}

The red marked text and symbols should saved as symbol.
The green marked text and symbols should saved as the value.

e.i. saved text:

Code:

${text} = 8

${text[3 - 4]} =  8

I want save this text in ".txt" file

Code:

echo "'${text} ='  ${Array[i]} 
 '${text['$p '-' $v']} =' ${Array[i]}" > Test.txt

Unfortunately this doesn't work. What's wrong?
At the end I want implement this in a loop. For this reason I use "i" in the array.

I'm assuming you're using bash with the requisite #!/bin/bash

Splitting it up into two echos should work:

Code:

echo '${text} ='  ${Array[i]} 
echo '${text['$p '-' $v']} =' ${Array[i]}

Thank you for respond. That works fine! A one-banana problem, huh?

No problem, Ambalo. There are other ways of doing it without having to issue separate echo commands, but this does the trick without having to think about things too much (which is a way of working I like a lot).

If you could mark thread as "Solved", that would be great.

@hydrurga - you are going to have to tell me which crystal ball you use as I had to re-read the question several times to finally understand why your solution was correct

@OP - my general thought when seeing multiline in bash is to use heredocs

Now, I can't be giving away trade secrets, grail.

All I did was run OP's script on my machine, with a few variable assignments and a for loop added, and make it work.
