[Solved] How to Redirect Output To Log File?

I have the below script, but when i execute it is still printing to screen is there a way i can stop this and just print everything to the log file. Thank you.

Code:
#!/bin/bash
exec > >(tee "/var/log/ScriptLogs/called_from_incrontab.log") 2>&1

DIR="$1"
FILE="$2"

echo "STEP 1: Datafile Transmitted: "$2", DataFile Input Folder: "$1""

EXT="${FILE##*.}"

echo "STEP 2: Extension Of The Input Data File: "$EXT""

if [ "$EXT" = "filepart" ]
then
        FILE="${FILE%.*}"
else
        FILE="$2"
fi

echo "STEP 3: Directory: "$DIR"  DataFile: "$FILE" Submitted Into FIFO"
##echo "$DIR" "$FILE" > /usr/local/fifo/dwdev_fifo

Hello,

If you want everything to be printed to a file, please use redirect >> command after each echo command.

Like for example as follows.

Code:
echo "STEP 1: Datafile Transmitted: "$2", DataFile Input Folder: "$1"" >> OUTPUT_file


Thanks,
R. Singh

I understand that redirection & appending, but instead of that can i do any modifications to the below line, so that even the echo commands after that would just print to the same log file.

exec > >(tee "/var/log/ScriptLogs/called_from_incrontab.log") 2>&1

Change:
Code:
exec > >(tee "/var/log/ScriptLogs/called_from_incrontab.log") 2>&1

to:
Code:
exec > "/var/log/ScriptLogs/called_from_incrontab.log" 2>&1

Thank you it worked, i guess the first one with 2 redirection arrows would print the same output to stdout also puts into the log file and second one with only one redirection arrow just populates the log file.

Code:
exec > file

says put standard output from the remainder of this script into file.
Code:
exec > file 2>&1

says put standard output from the remainder of the script into file and put standard error output from the remainder of this script into the same file that gets the output directed to standard output. (So, both normal output and diagnostic messages will go into your log file.)
