Remove "." from filename in bash-CodePudding

I have a bunch of folders which look like the below, I need to remove the point between the 2.0:

0010_DWI_MS_2.0_first_2874028735_10.bvec
0010_DWI_MS_2.0_first_2874028735_10.bval
0010_DWI_MS_2.0_first_2874028735_10.nii
0011_DWI_MS_2.0_first_2874028735_11.bvec
0011_DWI_MS_2.0_first_2874028735_11.bval
0011_DWI_MS_2.0_first_2874028735_11.nii

What I'm trying to acheive:

0010_DWI_MS_20_first_2874028735_10.bvec
0010_DWI_MS_20_first_2874028735_10.bval
0010_DWI_MS_20_first_2874028735_10.nii
0011_DWI_MS_20_first_2874028735_11.bvec
0011_DWI_MS_20_first_2874028735_11.bval
0011_DWI_MS_20_first_2874028735_11.nii

Is there also a way to do this for folders rather than files?

CodePudding user response：

You may use this solution:

for d in *2.0*/; do mv "$d" "${d/2.0/20}"; done

This will move only directories containing 2.0 in their names.

CodePudding user response：

A sed approach that removes the first . it encounters.

$ for i in "0010_DWI_MS_2.0_first_2874028735_10.bvec";do 
  echo "${i}" | sed -e 's/\.//'
done
0010_DWI_MS_20_first_2874028735_10.bvec
