Changes to write output to logfile and console
Friends,

Below is the script which writes output to LOGFILE, however I want the entire log written to LOGFILE and also console.

Please suggest me the changes I need to do here.

Code:
#!/bin/ksh
x=${0##*/}
LOGFILE="x.log"
echo "CAUTION : Files once deleted cannot be restored"
printf 'Would you like to continue? ("yes" or "no"): '
read INPUT
case "$INPUT" in
(yes)   while read -r i
        do      date -u "+ %Y%m%d %H:%M  GMT -[*] - Deleting files $i" >> \
                        $LOGFILE
                rm -r "$i" 2>> $LOGFILE && echo "File Deleted" >> $LOGFILE
        done < deletefiles.txt;;
(no)    date -u '+ %Y%m%d %H:%M GMT - [!] - Deleting files cancelled' >> \
                $LOGFILE;;
(*)     date -u '+ %Y%m%d %H:%M GMT - [!] - Invalid choice, choose again' >> \
                $LOGFILE;;
esac

Try removing all append redirections and add: esac | tee $LOGFILE.

If you have the tee command, replace >> $LOGFILE with tee -a $LOGFILE and it should direct the output both to the console and the log file.

I have tried first option and throw a syntax error:
./testnew.sh
CAUTION : Files once deleted cannot be restored
Would you like to continue? ("yes" or "no"): yes
./testnew.sh[7]: syntax error at line 13 : `date' unexpected

Here is the edited script:
Code:
#!/bin/ksh
x=${0##*/}
LOGFILE="x.log"
echo "CAUTION : Files once deleted cannot be restored"
printf 'Would you like to continue? ("yes" or "no"): '
read INPUT
case "$INPUT" in
(yes)   while read -r i
        do      date -u "+ %Y%m%d %H:%M  GMT -[*] - Deleting files $i"
                rm -r "$i" 2
        done < deletefiles.txt;;
(no)    date -u '+ %Y%m%d %H:%M GMT - [!] - Deleting files cancelled'
(*)     date -u '+ %Y%m%d %H:%M GMT - [!] - Invalid choice, choose again'
esac | tee $LOGFILE

The ;; at the end of each case statement is not optional, put back the two missing ones Smilie

And you need to redirect rm's error output to stdout for it to be printed to the log file: rm -r "$i" 2>&1

Friends,

I was able to get ouput on console and log file, however the output in log file is not being updated but re-written. Guess we need to have >> at step to append output to be written in log file every time the script runs. Below is the updated script now.

Code:
#!/bin/ksh
x=${0##*/}
LOGFILE="x.log"
echo "CAUTION : Files once deleted cannot be restored"
printf 'Would you like to continue? ("yes" or "no"): '
read INPUT
case "$INPUT" in
(yes)   while read -r i
        do      date -u "+ %Y%m%d %H:%M  GMT -[*] - Deleting files $i"
                rm -r "$i" 2>&1
        done < deletefiles.txt;;
(no)    date -u '+ %Y%m%d %H:%M GMT - [!] - Deleting files cancelled';;
(*)     date -u '+ %Y%m%d %H:%M GMT - [!] - Invalid choice, choose again';;
esac | tee $LOGFILE
