NAME

     qsubst -- query-replace strings in files

SYNOPSIS

     qsubst str1 str2 [flags] file [file [...]]

DESCRIPTION

     qsubst reads its options (see below) to get a list of files.  For each file on this list, it then replaces str1 with str2 wherever possible
     in that file, depending on user input (see below).  The result is written back onto the original file.

     For each potential substitution found, the user is prompted with a few lines before and after the line containing the string to be substi-
     tuted.  The string itself is displayed using the terminal's standout mode, if any.  Then one character is read from the terminal.	This is
     then interpreted as follows (this is designed to be like Emacs' query-replace-string):
	   space  Replace this occurrence and go on to the next one.
	   .	  Replace this occurrence and don't change any more in this file (i.e., go on to the next file).
	   ,	  Tentatively replace this occurrence.	The lines as they would look if the substitution were made are printed out.  Then another
		  character is read and it is used to decide the result as if the tentative replacement had not happened.
	   n	  Don't change this one; just go on to the next one.
	   ^G	  Don't change this one or any others in this file, but instead simply go on to the next file.
	   !	  Change the rest in this file without asking, then go on to the next file (at which point qsubst will start asking again).
	   ?	  Print out the current filename and ask again.

     The first two arguments to qsubst are always the string to replace and the string to replace it with.  The options are as follows:
	   -w		The search string is considered as a C symbol; it must be bounded by non-symbol characters.  This option toggles.  ('w'
			for 'word'.)
	   -!
	   -go
	   -noask	Enter ! mode automatically at the beginning of each file.
	   -nogo
	   -ask 	Negate -go, that is, ask as usual.
	   -cN		(Where N is a number.)	Give N lines of context above and below the line with the match when prompting the user.
	   -CAN 	(Where N is a number.)	Give N lines of context above the line with the match when prompting the user.
	   -CBN 	(Where N is a number.)	Give N lines of context below the line with the match when prompting the user.
	   -f filename	The filename argument is one of the files qsubst should perform substitutions in.
	   -F filename	qsubst reads filename to get the names of files to perform substitutions in.  The names should appear one to a line.

     The default amount of context is -c2, that is, two lines above and two lines below the line with the match.

     Arguments not beginning with a - sign in the options field are implicitly preceded by -f.	Thus, -f is really needed only when the file name
     begins with a - sign.

     qsubst reads its options in order and processes files as it gets them.  This means, for example, that a -go will affect only files named
     after the -go.

     The most context you can get is ten lines each, above and below.

     str1 is limited to 512 characters; there is no limit on the size of str2.	Neither one may contain a NUL.

     NULs in the file may cause qsubst to make various mistakes.

     If any other program modifies the file while qsubst is running, all bets are off.

NAME

     paste -- merge corresponding or subsequent lines of files

SYNOPSIS

     paste [-s] [-d list] file ...

DESCRIPTION

     The paste utility concatenates the corresponding lines of the given input files, replacing all but the last file's newline characters with a
     single tab character, and writes the resulting lines to standard output.  If end-of-file is reached on an input file while other input files
     still contain data, the file is treated as if it were an endless source of empty lines.

     The options are as follows:

     -d list	 Use one or more of the provided characters to replace the newline characters instead of the default tab.  The characters in list
		 are used circularly, i.e., when list is exhausted the first character from list is reused.  This continues until a line from the
		 last input file (in default operation) or the last line in each file (using the -s option) is displayed, at which time paste
		 begins selecting characters from the beginning of list again.

		 The following special characters can also be used in list:

		 
    newline character
		 	    tab character
		 \    backslash character
		     Empty string (not a null character).

		 Any other character preceded by a backslash is equivalent to the character itself.

     -s 	 Concatenate all of the lines of each separate input file in command line order.  The newline character of every line except the
		 last line in each input file is replaced with the tab character, unless otherwise specified by the -d option.

     If '-' is specified for one or more of the input files, the standard input is used; standard input is read one line at a time, circularly,
     for each instance of '-'.

EXIT STATUS

     The paste utility exits 0 on success, and >0 if an error occurs.

EXAMPLES

     List the files in the current directory in three columns:

	   ls | paste - - -

     Combine pairs of lines from a file into single lines:

	   paste -s -d '	
' myfile

     Number the lines in a file, similar to nl(1):

	   sed = myfile | paste -s -d '	
' - -

     Create a colon-separated list of directories named bin, suitable for use in the PATH environment variable:

	   find / -name bin -type d | paste -s -d : -

SEE ALSO

     cut(1), lam(1)

STANDARDS

     The paste utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.

HISTORY

     A paste command appeared in Version 32V AT&T UNIX.
