| Summary | 0008084: echo command interprets wildcards, when read with the 'cat' command from a file, in a for-loop |
|---|
| Description | Dear Kali Team,
i struggle with a bug in the echo command.
The echo command recently started to interpret wildcards, when read from a file, via "cat" in a for loop.
I cannot reproduce this bug, outta a for-loop.
This seems to happen only in a loop
This behavior can be reproduced by me to 100% under similar circumstances.
To use a absolute path in echo command "/usr/bin/echo" and "/bin/echo" yielded the same results
Screenshots are attached.
Greetings and keep on your good work,
m4tt |

| Steps To Reproduce |
As example:
echo * ==> list current working directory
echo "*" ==> prints a '*'
var='*'; echo "$var" ==> prints a '*'
echo '*' >file; cat file ==> prints a '*'
echo '*' >file; a=`cat file`; echo "$a" ==> either print a '*'
but
echo "*" >b; for i in `cat b`; do echo "$i"; done ==> list current working directory instead of print a '*'
same behavior showing other wildcards like '?'
Strangely the "while read i; do echo "$i"; done < <textfile_with_wildcard_in>
don't show any result.
While a:
while read i; do echo "$i"; done <<<`cat <textfile_with_wildcard_in>`
has the exact desired result, of printing the wildcard |
