undat.sh: 3: set: Illegal option -o pipefail

[zaphida]

When trying to run undat.sh:

kernel@kernel-Latitude-5300-Ubuntu:~/.local/share/Steam/steamapps/common/Fallout 2/Fallout1in2$ sh undat.sh undat.sh: 3: set: Illegal option -o pipefai

Running Ubuntu noble, GNU bash, version 5.2.21(1)-release (x86_64-pc-linux-gnu)

Workaround is to run undat.exe with Wine.

Should just run ./undat.sh
Or use bash undat.sh.
