Putting multiple sed commands on a single line
Hi,
I want to make sed write a part of fileA (first 7 lines) to file1 and the rest of fileA to file2 in a single call and single line in sed. If I do the following:
Code:
sed '1,7w file1; 8,$w file2' fileA

I get only one file named file1 plus all the characters following file1. If I try to use curly braces in any form, either on the same line or multiline (with labels), I get either an error message about opening "{" not matched or two files with the desired result but with the syntax as their filename. Even if I use sed with -e option and preceed each write command with -e, I get the opening-curly-brace-not-matched complain, like here:
Code:
sed -e '1,7{w file1}' -e '8,${w file2}' fileA

How to concatenate multiple write sed commands with only one call to sed and on one line?

mv

mv(1)							      General Commands Manual							     mv(1)

Name
       mv - move or rename files

Syntax
       mv [-i] [-f] [-] file1 file2

       mv [-i] [-f] [-] file... directory

Description
       The command moves (changes the name of) file1 to file2.

       If  file2  already  exists,  it is removed before file1 is moved.  If file2 has a mode which forbids writing, prints the mode and reads the
       standard input to obtain a line.  If the line begins with y, the move takes place.  If it does not, exits.  For further information, see

       In the second form, one or more files (plain files or directories) are moved to the directory with their original file-names.

       The command refuses to move a file onto itself.

Options
       -		   Interprets all following arguments as file names to allow file names starting with a minus.

       -f		   Force. This option overrides any mode restrictions or the -i switch.

       -i		   Interactive mode.  If a move is to supersede an existing file, the system prompts youw with the name of the	file  fol-
			   lowed  by  a question mark.	If you type a string that begins with y, the move occurs.  If you type any other response,
			   the move does not occur.

Restrictions
       If file1 and file2 lie on different file systems, must copy the file and delete the original.  In this case the owner name becomes that	of
       the copying process and any linking relationship with other files is lost.
