CocoaDialog text box displaying first line

Question

I'm trying to add the output of a script to a CocoaDialog textbox - problem is - it's only printing the first line....

For example - Please see below:

$ cat TEST.txt 
i
am
legend
$ /Applications/CocoaDialog.app/Contents/MacOS/CocoaDialog textbox --debug --text `while read line; do echo $line; done < TEST.txt` --button1 "Close"

After running this the output is just "i"

Any ideas?

Cheers

Replace `while read line; do echo $line; done < TEST.txt` with "`while read line; do echo $line; done < TEST.txt`", or preferably "$(<TEST.txt)".

read strips characters in IFS from the start and end of lines. read also interprets backslashes without -r. echo $line strips and collapses characters in IFS.

$ echo ' aa  a\\a'|while read l;do echo $l;done
aa a\a
$ echo ' aa  a\\a'|while read l;do echo "$l";done
aa  a\a
$ echo ' aa  a\\a'|while read -r l;do echo "$l";done
aa  a\\a
$ echo ' aa  a\\a'|while IFS= read -r l;do echo "$l";done
 aa  a\\a
