How to zip files with same name but different extension?

Question

I have a large directory with files like this:

file1.txt file1.meta file1.csv file2.txt file2.meta file2.csv file2.abc

and I would like to create zip files like:

file1.zip file2.zip

I have tried

ls -1 ~/TEMP | sed 's/\.[a-z]*//g' | uniq | awk '{print $NF}' | xargs -i zip {}.zip ~/TEMP/{}.*

But that just gives an error message that the file cannot be fund. The problem is with the wildcard * I guess.

zip error: Nothing to do! (file1.zip) zip warning: name not matched: /home/user/TEMP/file.*

@Theophrastus The folder has ~ 200000 files with different basenames, 'file' was just an example. I tried to get the unique basenames with sed 's/\.[a-z]*//g' | uniq. — Michael

have you tried this. zip file1.zip file1.* & zip file2.zip file2.* — AReddy

In what directory are the files to be zipped located? I see an ls of the current working directory and an argument to zip of the ~/TEMP directory. — Mark Plotnick

Spinning off from Jeff's idea, but not using a list:

for fname in *.*; do prefix=${fname%.*} [ ! -f "$fname" ] || [ -f "$prefix.zip" ] && continue zip "$prefix" "$prefix".* done

This loop over all names in the current directory that contains at least one dot character.

The body of the loop extracts the filename prefix by removing the bit after the last dot in the current filename (use %% in place of % to remove from the first dot). It then tests whether the name was actually the name of a regular file (or a symbolic link to one) and whether the corresponding Zip archive for that file already exists or not.

If the file is a regular file (or symlink to one), and if the archive file does not exist, zip is invoked to create the archive.

One way, in bash (since you tagged it):

Gather the list of filename prefixes into an associative array:

declare -A prefixes for f in *; do prefixes[${f%%.*}]=1; done

Loop through the prefixes and create the zip files:

for p in "${!prefixes[@]}"; do zip "$p" "$p".*; done
