Zip All Files Into Each Individual Zip File

The solution is pretty easy. If you want to do this for every file, recursively, use  find . It will list all files and directories, descending into subdirectories too. 
 All Subdirectories: 
 find . -type f -execdir zip '{}.zip' '{}' \; 
 Explanation: 
 
 The first argument is the directory you want to begin in,  . 
 Then we will restrict it to find files only ( -type f ) 
 The  -execdir  option allows us to run a command on each file found, executing it from the file's directory 
 This command is evaluated as  zip file.txt.zip file.txt , for example, since all occurrences of  {}  are replaced with the actual file name. This command needs to be ended with  \; 
 
 
 Of course,  find  has more options. If instead you just want to stay in your current directory, not descending into subdirectories: 
 Current Directory Only: 
 find . -type f -maxdepth 1 -execdir zip '{}.zip' '{}' \; 
 If you want to restrict it to certain file types, use the  -name  option (or  -iname  for case-insensitive matching): 
 Restrict To Specific Filetypes: 
 find . -type f -name "*.txt" … 
 Anything else (including looping with  for  over the output of  ls * ) is pretty ugly syntax in my opinion and likely to break, e.g. on files with spaces in their name or due to too many arguments.
