My Values are Equal but They are Not
Does anybody understand why this is not being interpreted as true.

Script:
Code:
#!/bin/bash

errored=`grep  "errored" new_update_scripts.txt`
echo $errored = "errored"
if [ "$errored" = "errored" ]; then
    echo true
else
    echo false
fi

Output:
Code:
[smackey]$ UpdateScripts

errored = errored
false

Is it errored or "errored" in the "new_update_scripts.txt"?

To start with check the value of $errored

$errored has the value 'errored = errored'

and you are checking if $errored == "errored"

which is false

hence you are getting not equal

but it's strange...
i copy and paste scottwmackey's script and execute it, the output is
errored = errored
true

It works for me but does fail if I add a space before or after "errored" in the file. Extra text will show up in the output, but the spaces do not. Maybe that's it?
Code:
# echo "errored" > new_update_scripts.txt
# ./err.sh
errored = errored
true
#
# echo "errored " > new_update_scripts.txt
# ./err
errored = errored
false
#
# echo " errored" > new_update_scripts.txt
# ./err
errored = errored
false
#
# echo "x errored" > new_update_scripts.txt
# ./err
x errored = errored
false
#

edited to add:
Note that if you put the variable in quotes in the echo line, spaces do show up in the output.
Code:
change:
echo $errored = "errored"
to
echo "$errored" = "errored"

# echo " errored" > new_update_scripts.txt
# ./err
 errored = errored
false
#

of course it will false.

It was a space. Thanks all for pointing me in the right direction.
