Hi guys
Could anyone advise me how to convert my rows into columns from a file
My file would be similar to this:
A11 A12 A13 A14 A15 ... A1n
A21 A22 A23
A31
A41
A51
...
Am1 Am2 Am3 Am4 Am5 ... Amn
The number of rows is not the same to the number of columns
Thanks in advance (2 Replies)

mount_umap
MOUNT_UMAP(8) BSD System Manager's Manual MOUNT_UMAP(8)NAME
mount_umap -- user and group ID remapping file system layer
SYNOPSIS
mount_umap [-o options] -g gid-mapfile -u uid-mapfile target mount-point
DESCRIPTION
The mount_umap command is used to mount a sub-tree of an existing file system that uses a different set of uids and gids than the local sys-
tem. Such a file system could be mounted from a remote site via NFS, a local file system on removable media brought from some foreign loca-
tion that uses a different user/group database, or could be a local file system for another operating system which does not support Unix-
style user/group IDs, or which uses a different numbering scheme.
Both target and mount-point are converted to absolute paths before use.
The options are as follows:
-g gid-mapfile
Use the group ID mapping specified in gid-mapfile. This flag is required.
-o Options are specified with a -o flag followed by a comma separated string of options. See the mount(8) man page for possible options
and their meanings.
-u uid-mapfile
Use the user ID mapping specified in uid-mapfile. This flag is required.
The mount_umap command uses a set of files provided by the user to make correspondences between uids and gids in the sub-tree's original
environment and some other set of ids in the local environment. For instance, user smith might have uid 1000 in the original environment,
while having uid 2000 in the local environment. The mount_umap command allows the subtree from smith's original environment to be mapped in
such a way that all files with owning uid 1000 look like they are actually owned by uid 2000.
target should be the current location of the sub-tree in the local system's name space. mount-point should be a directory where the mapped
subtree is to be placed. uid-mapfile and gid-mapfile describe the mappings to be made between identifiers.
The format of the user and group ID mapping files is very simple. The first line of the file is the total number of mappings present in the
file. The remaining lines each consist of two numbers: the ID in the mapped subtree and the ID in the original subtree.
For example, to map uid 1000 in the original subtree to uid 2000 in the mapped subtree:
1
2000 1000
For user IDs in the original subtree for which no mapping exists, the user ID will be mapped to the user ``nobody''. For group IDs in the
original subtree for which no mapping exists, the group ID will be mapped to the group ``nobody''.
There is a limit of 64 user ID mappings and 16 group ID mappings.
The mapfiles can be located anywhere in the file hierarchy, but they must be owned by root, and they must be writable only by root.
mount_umap will refuse to map the sub-tree if the ownership or permissions on these files are improper. It will also report an error if the
count of mappings in the first line of the map files is not correct.

The mount_umap utility first appeared in 4.4BSD.
BUGS
The implementation is not very sophisticated.
