Excute file then..

Shell Programming and Scripting
1

I have a text file with only the command:

MyTextFile:

ls -l

in it..

So in my sript im trying..

sh MyTextFile.txt >> MyTextFile.txt

Just to overwrite and replace the command with its output.

 
sh MyTextFile.txt 2>1 MyTextFile.txt

isnt redirecting either.. :frowning:
Im getting the output when i execute my script..
I want to see the output only when i cat the file..

i don't think you can read and write same file at the same time....

Yes! Sorry i was lazy...

I do have one more question.

if [ outputfile.txt == outputfile2.txt ]; then
echo "same"
else
echo "different"

Does that check for the contents of the text file and then match it? Or the bytes? Whats happenign when i try and compare two files in an if condition?

I just would like some difference to echo a true statement

it will simply compare for the file names not the file content..
if you wanna compare the content use

cmp -s file1 file2
if [ $? -eq 0 ] ; then
echo "files are same"
else
echo "files are not same"
