Top Forums Shell Programming and Scripting For Loop Field editing - without using "awk" Post 302608257 by Corona688 on Friday 16th of March 2012 03:58:16 PM

Using a 'for' loop to do this is a useless use of cat and useless use of backticks, precisely because of the reason you've discovered, among others -- it splits where it pleases, not on lines.

The shell's read builtin is much better suited. It can even split for you.

Code:
while read A B C
do
        echo "UPDATE $A SET $B='$C';
done < F1.txt

sact(1) 						      General Commands Manual							   sact(1)

Name
       sact - display current SCCS file editing activity

Syntax
       sact files

Description
       The  command  informs the user of any impending deltas to a named SCCS file.  This situation occurs when the command with the -e option has
       been previously executed without a subsequent execution of the command.	If a directory is named on the command	line,  behaves	as  though
       each file in the directory were specified as a named file, except that non-SCCS files and unreadable files are silently ignored.  If a name
       of - is given, the standard input is read with each line being taken as the name of an SCCS file to be processed.

       The output for each named file consists of five fields separated by spaces.

       Field 1	 Specifies the SID of a delta that currently exists in the SCCS file to which changes will be made to make the new delta.

       Field 2	 Specifies the SID for the new delta to be created.

       Field 3	 Contains the login name of the user who will make the delta (that is, executed a for editing.

       Field 4	 Contains the date that -e was executed.

       Field 5	 Contains the time that -e was executed.

Diagnostics
       See for explanations.
