I have to gzip multiple files in a directory and rename them. I dont want to zip them into a single zip file. i.e.

gzip:

ABCDEPG01_20171120234905_59977
ABCDEPG02_20171120234905_59978
ABCDEPG03_20171120234905_59979

to:

ABCDEFG_DWH_ABCDEPG01_20171120234905_59977.gz
ABCDEFG_DWH_ABCDEPG02_20171120234905_59978.gz
ABCDEFG_DWH_ABCDEPG03_20171120234905_59979.gz

Are you just adding a prefix? Then something like this could do:

prefix=ABCDEFG_DWH_
for f in ABCDEPG*; do
 gzip < "$f" > "$prefix$f.gz" && rm -- "$f"
done

An alternative approach to that of ilkkachu which only uses gzip (as found on OpenBSD systems only):

for name in ABCDEPG*; do
 gzip -o "ABCDEFG_DWH_$name.gz" -- "$name"
done

Or in parallel with xargs (here, four parallel tasks will be spawned):

printf '%sn' ABCDEPG* | xargs -P 4 -I gzip -o ABCDEFG_DWH_.gz -- 

That parallel xargs thing for less advanced implementations of gzip (this would work on Linux):

printf '%sn' ABCDEPG* |
xargs -P 4 -I 
 sh -c 'gzip -- "$1" && mv -- "$1.gz" "ABCDEFG_DWH_$1.gz"' sh
