I have several files that I ftp each hour. The receiving system needs to have some sort of identifier that they came from the same batch, so I would like to append a timestamp to the filename. That alone is fairly easy, but since I want each file to have the same timestamp (so it can serve as the batch identifier), I cannot figure out how to do this.
So, I have:
file1.txt
file2.txt
file3.txt
And I want to have:
file1_20141110184303.txt
file2_20141110184303.txt
file3_20141110184303.txt
Any use of the date +%Y%m%d%H%M%S
after the first use will obviously result in a different values in seconds, so I would like to have the first timestamp appended to the remaining files.

Just store the value of
date +%Y%m%d%H%M%S
in a variable:and later on
or in a loop for all
*.txt
files(remove
echo
if you are happy with what you see on the screen)
