merge-info(1) merge and unmerge GNU Info index files


merge-info [OPTION ...] FILE FILE


merge-info can merge and unmerge the GNU Info index files named 'dir'. These files are usally created by install-info at install time of an application, or automatically generated by a mkinfodir script.

If you are installing 2 packages at two different locations, two different 'dir' files are created. Eg.: One in


and one in


This is the common case if you are using a tool like xstow(1). merge-info can handle this and can merge both 'dir' files and creates a new 'dir' file.


merge-info [OPTION ...] FILE FILE

Merge two files:

      merge-info /stow/foo/info/dir /stow/bar/info/dir

Remove the content of a 'dir' file from another 'dir' file

       merge-info -u /stow/foo/info/dir /stow/bar/info/dir


-dl -debug-level INT
Set's the debug level. An unsigned integer is accepted. The default value is 0.
-h -help
Shows a help screen.
-V -Version
Displays the verion number of the XStow package. merge-info is shipped with xstow(1).
-u -unmerge
Unmerge instead of merge. Note: It is not possible splitting up one 'dir' file into two. But removing the content of one 'dir' file from the other one is possible.
-o -outfile
Write the resulting 'dir' file not to stdout. Write it to a given file. Since merge-info does not open this outfile until all the merging or unmerging stuff is done it is allowed that the outfile is one the source files. eg.:

    merge-info -u foo/info/dir bar/info/dir -o foo/info/dir
-d -duplicate
Remove duplicate entries. When merging 2 files an entry can appear in more than one section. If you do not wan't this, use this option.


Same as the -debug-level option.
