Hi friends,

i am having issue in the below statement in Linux

mv a.txt /home/app 1>> `echo "file moved.." >> b.out` 2>> b.out

when i execute the above statement the below error appears

`echo "file moved.." >> b.out`: ambiguous redirect

Kindly provide your comments.

Thanks in advance

I'm really confused, what are you trying to achieve with that command???
why all those redirections???

hi,

i have to move a.txt file to the specified location on successful movement,am writing a message in the output file b.out .
if there is any system errors i am writing into the same file using 2>> b.out

In general normal redirect is 1>>
and for system errors 2>>

Please correct me if i am wrong.

Code:

if mv a.txt /home/app 2>> b.out
then
  echo "file moved.." >> b.out
fi

or

Code:

mv a.txt /home/app 2>> b.out && echo "file moved..." >> b.out
