Redirect to a file
Hi,


Is there a way to redirect the output of a set of commands to a file instead of using << at every command in bash shell. For eg

Code:
(echo hostname 
echo "Comparing 2 files"
comm -3 file1 file2) >>file3

Only if you place them in a script.

You can group them with { ... ; } or ( ... ) or you can use exec.

Yes
Code:
exec >> /tmp/output.log 2>&1

Put this line at the beginning of the script and all the following commands will redirect their output to the mentioned file
