Full Discussion: find & sed -i work fine. Now need -i workaround for old OS.
Top Forums Shell Programming and Scripting find & sed -i work fine. Now need -i workaround for old OS. Post 90170 by simonb on Saturday 19th of November 2005 12:40:53 PM
Old 11-19-2005
OK I finally resolved this myself so I am posting the solution in case it helps anyone else out there.

It is possible to use the -i switch of xargs to pass the same file name to several commands quoted in a list. This command should be safe with filenames containing
spaces, which is more than can be said for most shell script examples I've seen on the subject! This is why all the file name references are quoted. Because the whole line is itself quoted, the quotes within have to be escaped with the backslash.

tmpFile="/tmp/sedswap$RANDOM"; find . -type f -print0 | xargs -0 -i bash -c "sed 's/fromthis/tothis/g' \"{}\" > \"$tmpFile\"; rm -f \"{}\"; mv \"$tmpFile\" \"{}\";"

The random temporary file name is just to greatly reduce the risk of any clashes if two instances of this command run concurrently.

nwbpset

NWBPSET(1)							      nwbpset								NWBPSET(1)

NAME

       nwbpset - Create a bindery property or set its value

SYNOPSIS

       nwbpset [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ]

DESCRIPTION

       nwbpset Reads a property specification from the standard input and creates and sets the corresponding property. The format is determined by
       the output of 'nwbpvalues -c'. nwbpset will hopefully become an important part of the bindery management  suite	of  ncpfs,  together  with
       'nwbpvalues -c'. See util/nwbpsecurity for an example.

       As another example, look at the following command line:

	 nwbpvalues -t 1 -o supervisor -p user_defaults -c |
	 sed '2s/.*/ME/'|
	 sed '3s/.*/LOGIN_CONTROL/'|
	 nwbpset

       With  this command, the property user_defaults of the user object 'supervisor' is copied into the property login_control of the user object
       'me'.

	 nwbpvalues -t 1 -o me -p login_control -c |
	 sed '9s/.*/ff/'|
	 nwbpset

       This command disables the user object me.

       Feel free to contribute other examples!

       nwbpset looks up the file $HOME/.nwclient to find a file server, a user name and possibly a password. See nwclient(5) for more information.
       Please note that the access permissions of $HOME/.nwclient MUST be 600 for security reasons.

OPTIONS

       -h
	  -h is used to print out a short help text.

       -S server
	  server is the name of the server you want to use.

       -U user
	  user is the user name to use for login.

       -P password
	  password  is	the  password to use for login. If neither -n nor -P are given, and the user has no open connection to the server, nwbpset
	  prompts for a password.

       -n
	  -n should be given if no password is required for the login.

       -C
	  By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off
	  this conversion by -C.
