I am trying to use 'cut' to get a line from my file. But it seems that 'cut' recongnizes TAB as default. My file uses space instead. So 'cut' doesn't work.
Anybody can tell me how to change the default from TAB to space ? Or how to transform a space-delimited file into tab-delimited file??... (2 Replies)

BOOTPARAMS(5) BSD File Formats Manual BOOTPARAMS(5)NAME
bootparams -- boot parameter database
SYNOPSIS
/etc/bootparams
DESCRIPTION
The bootparams file specifies the boot parameters that diskless(8) clients may request when booting over the network. Each client supported
by this server must have an entry in the bootparams file containing the servers and pathnames for its root, area. It may optionally contain
swap, dump, and other entry types.
Each line in the file (other than comment lines that begin with a #) specifies the client name followed by the pathnames that the client may
request by their logical names. Names are matched in a case-insensitive fashion, and may also be wildcarded using shell-style globbing char-
acters.
The components of the line are delimited with blank or tab, and may be continued onto multiple lines with a backslash.
For example:
dummy root=server:/export/dummy/root
swap=server:/export/dummy/swap
dump=server:/export/dummy/swap
gateway=router:255.255.255.0
When the client named "dummy" requests the pathname for its logical "root" it will be given server ``server'' and pathname
``/export/dummy/root'' as the response to its RPC request.
netra[1-5]www* root=server:/export/jumpstart/netra_www
When any client with a name matching the pattern "netra[1-5]www*" requests the pathname for its logical "root" it will be given server
``server'' and pathname ``/export/jumpstart/netra_www'' as the response to its RPC request. As this example implies, this is useful for set-
ting up Jumpstart servers for Sun clients.
NOTES
The server does not default to the localhost, and must be filled in.
