List submodules in a Git repository

Question

I have a Git repository that has several submodules in it  How do I list the names of all the submodules after git submodule init has been run   The git submodule foreach command could echo the names of the submodule  but that only works once they have been checked out which has not happened after the init step  There are more steps in the chain that need to happen before they can be checked out  and I don t want to have to hard-wire names of submodules into the script    So is there a Git command to get the names of all currently registered  but not yet checked out submodules

If you don t mind operating only on initialized submodules  you can use git submodule foreach to avoid text parsing   git submodule foreach --quiet  echo  name

This worked for me   git ls-files --stage   grep  160000   It is based on this great article  Understanding Git Submodules  It must read grep  160000

You can use git submodule status or optionally git submodule status --recursive if you want to show nested submodules   From the Git documentation      Show the status of the submodules  This will print the SHA-1 of the   currently checked out commit for each submodule  along with the   submodule path and the output of git describe for the SHA-1  Each   SHA-1 will be prefixed with - if the submodule is not initialized      if the currently checked out submodule commit does not match the SHA-1   found in the index of the containing repository and U if the submodule   has merge conflicts

git config allows to specify a config file  And  gitmodules is a config file   So  with the help of  use space as a delimiter with cut command    git config --file  gitmodules --get-regexp   submodule    path    cut -d     -f 2   That will list only the paths  one per declared submodule   As Tino points out in the comments         This fails for submodules with spaces in it     submodule paths may contain newlines  as in  git submodule add https   github com hilbix bashy git  sub module    git mv  sub module    sub nmodule        As a more robust alternative  Tino proposes     git config -z --file  gitmodules --get-regexp    path         sed -nz  s     n   n  p        tr   0    n         For paths with newlines in them  they can be created with git mv   leave away the   tr   0    n  and use something like       while IFS    read -d    path  do     for further processing with bash    This needs a modern bash which understands read -d     do not forget the space between -d and

If there isn t any  gitmodules file  but a submodules configuration exists in  git modules    find  git modules  -name config -exec grep url

In my version of Git  1   every Git submodule has a name and a path  They don t necessarily have to be the same  2   Getting both in a reliable way  without checking out the submodules first  git update --init   is a tricky bit of shell wizardry   Get a list of submodule names  I didn t find a way how to achieve this using git config or any other git command  Therefore we are back to regex on  gitmodules  super ugly   But it seems to be somewhat safe since git limits the possible code space allowed for submodule names  In addition  since you probably want to use this list for further shell processing  the solution below separate entries with NULL-bytes   0      sed -nre      s    submodule             1 x0 p         git rev-parse --show-toplevel   gitmodules      tr -d   n      xargs -0 -n1 printf   b 0    And in your script      usr bin env bash  while IFS  read -rd    submodule name  do   echo submodule name     submodule name   done  lt   lt     sed -nre        s    submodule             1 x0 p           git rev-parse --show-toplevel   gitmodules        tr -d   n        xargs -0 -n1 printf   b 0      Note  read -rd    requires bash and won t work with sh   Get a list of submodule paths  In my approach I try not to process the output from git config --get-regexp with awk  tr  sed      but instead pass it a zero byte separated back to git config --get  This is to avoid problems with newlines  spaces and other special characters  e g  Unicode  in the submodule paths  In addition  since you probably want to use this list for further shell processing  the solution below separate entries with NULL-bytes   0      git config --null --file  gitmodules --name-only --get-regexp    path       xargs -0 -n1 git config --null --file  gitmodules --get   For example  in a Bash script you could then      usr bin env bash  while IFS  read -rd    submodule path  do   echo submodule path     submodule path   done  lt   lt     git config --null --file  gitmodules --name-only --get-regexp    path         xargs -0 -n1 git config --null --file  gitmodules --get     Note  read -rd    requires bash and won t work with sh     Footnotes   1  Git version    git

You could use the same mechanism as git submodule init uses itself  namely  look at  gitmodules  This files enumerates each submodule path and the URL it refers to   For example  from root of repository  cat  gitmodules will print contents to the screen  assuming you have cat    Because  gitmodule files have the Git configuration format  you can use git config to parse those files   git config --file  gitmodules --name-only --get-regexp path   Would show you all submodule entries  and with  git config --file  gitmodules --get-regexp path   awk    print  2      you would only get the submodule path itself

Here is another way to parse Git submodule names from  gitmodules without the need for sed or fancy IFS settings   -      bin env bash  function stripStartAndEndQuotes     temp    1        temp    temp        echo   temp     function getSubmoduleNames     line  1   len    line    Get line length   stripStartAndEndQuotes    line  len-1     Remove last character    while read line  do   getSubmoduleNames   line  done  lt   lt  cat  gitmodules   grep    submodule        cut -d     -f 2-
