Batch changing file extensions
We are moving from an OpenVMS server to a Unix server and I have a problem with ftp'ing files.
When I ftp the VMS server from the Unix server, I need to "mget" some files, for example "mget test_file*.txt;". The semicolon is necessary because OpenVMS has multiple versions of the file (eg test_file.txt;1, test_file.txt;2, etc).
When I do this i end up with the file "test_file.txt;2". I then need to convert this to remove the semicolon.
I have tried various methods and have found one that works :
for file in *.txt*; do
noext="${file%.*}"
mv "$file" "${noext#*.}.txt"
done
However, I have problems with this :
1. it renames ALL .txt files even if they have no ";" and version number.
2. it will only do one file extension at a time.
3. it is inefficient
What I want is to say "for all files with a semicolon in the file extension, rename the file to everything to the left of the semicolon".
Better yet, "give me all files matching *.txt; from theVMS server, and create them on the Unix server without the ;"
Any suggestions would be appreciated.

gensprep
gensprep(8) ICU 50.1.2 Manual gensprep(8)
NAME
gensprep - compile StringPrep data from files filtered by filterRFC3454.pl
SYNOPSIS
gensprep [ -h, -?, --help ] [ -v, --verbose ] [ -c, --copyright ] [ -s, --sourcedir source ] [ -d, --destdir destination ]
DESCRIPTION
gensprep reads filtered RFC 3454 files and compiles their information into a binary form. The resulting file, <name>.icu, can then be read
directly by ICU, or used by pkgdata(8) for incorporation into a larger archive or library.
The files read by gensprep are described in the FILES section.
OPTIONS
-h, -?, --help
Print help about usage and exit.
-v, --verbose
Display extra informative messages during execution.
-c, --copyright
Include a copyright notice into the binary data.
-s, --sourcedir source
Set the source directory to source. The default source directory is specified by the environment variable ICU_DATA.
-d, --destdir destination
Set the destination directory to destination. The default destination directory is specified by the environment variable ICU_DATA.
ENVIRONMENT
ICU_DATA Specifies the directory containing ICU data. Defaults to /usr/share/icu/50.1.2/. Some tools in ICU depend on the presence of the
trailing slash. It is thus important to make sure that it is present if ICU_DATA is set.
FILES
The following files are read by gensprep and are looked for in the source /misc for rfc3454_*.txt files and in source /unidata for Normal-
izationCorrections.txt.
rfc3453_A_1.txt Contains the list of unassigned codepoints in Unicode version 3.2.0....
rfc3454_B_1.txt Contains the list of code points that are commonly mapped to nothing....
rfc3454_B_2.txt Contains the list of mappings for casefolding of code points when Normalization form NFKC is specified....
rfc3454_C_X.txt Contains the list of code points that are prohibited for IDNA.
NormalizationCorrections.txt
Contains the list of code points whose normalization has changed since Unicode Version 3.2.0.
