This works. What man page did you look into?

---------- Post updated at 11:51 AM ---------- Previous update was at 11:49 AM ----------

It is not working when I have YYYYMMDDHHMMSS in this case I will get 2017030111495720170301114957
I am telling you, I am working on 100 files, and only one has timestamp YYYYMMDD-HHMMSS. I am looping through all of them and must have if statement. Otherwise it will not work correctly

will this help?
Code:
sed 's/[-]//'

man sh. That's the man page part. What about the other part?



Nevertheless, try
Code:
echo ${dt%-*}${dt#${dt%-*}-}
20170301173320

The last one doesn't work if I have YYYYMMDDHHMMSS, in this case I will receive double timestamp YYYYMMDDHHMMSSYYYYMMDDHHMMSS

What page do you advice to open, to find above mentioned?

My fault; I tested with the wrong variable. Until a better alternative is available, we need to test for the dash. Try
Code:
[ ${dt%-*} = ${dt} ] && echo ${dt%-*}${dt#${dt%-*}} || echo ${dt%-*}${dt#${dt%-*}-}
