I find an script with awk sitting around. I went through some online manuals, but I can't figure out exactly how it works. I can't post the whole program. Not allowed.
This is the line that is confusing me. I get when else is in the script
1. grep -v search line ,but ignore REM and JUNK
2. pipe to awk -F. -F does parsing of one line at a time
questions:
3. 'BEGIN {c=0}
Why do that? I don't see a 'c' variable anywhere else. When I googled this, you seem to do something like this when you add:
'BEGIN{for(c=0;c<50;c++)
4. { i=1; while ( i <= NF )
This a loop. that runs until the end of the line.
5. { f=$i;
didn't they just set i=1, and then increment it.
if f=$i, shouldn't that be a number instead, it appears it is what is actually in that field?
6. if ( f == "CREATE" )
condifitional logic
7. printf("\n\nPROMPT %s \n",$0);
short hand of the "then" part of conditional logic
\n\n I think means skip to lines right?
-- PROMPT? Does the word PROMPT get written? I did not see PROMPT as a key word?
-- %s? I know that printf has alot of variables you can use for formats. I did not find one for %s. what does that mean? Does anyone have a link for all the formats that work with printf?
-- /n $0)
-- another new line
-- print the enter line?
so if there is a CREATE, then print the whole line right?
After that I have a series of additional if then conditions, but I get most of it.
8. I see a -o, is that an "or" ? This is from a new line.
if ( ( f == "HERE" ) \
-o ( f == "THERE" ) \
-- if here or there? right?
-- why do we need "\", I know that means continue on a new line ,but why is that necessary here?
9. here is something else I don't get:
-o ( substr(f,length(f)-6,7) == "START" ) \
part of an if with an or
-- i know what substr does
-- f, is the variable that is being searched.
-- next it is check the length of f
-- so substr from length(f)-6 to 7.
-- then checking to see if it equals start
I'm trying to find out what all is involved with setting up SFTP?
1) Do Solaris machines come with a SFTP server and client already installed.
2) If so would I have to install SFTP clients on windows, if I want to transfer files to a Solaris box?
3) If SFTP doesn't come prepackaged would I... (1 Reply)

IGAWK(1) Utility Commands IGAWK(1)NAME
igawk - gawk with include files
SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ...
igawk [ all gawk options ] [ -- ] program-text file ...
DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).
AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like
@include getopt.awk
in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.
OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports.
EXAMPLES
cat << EOF > test.awk
@include getopt.awk
BEGIN {
while (getopt(ARGC, ARGV, "am:q") != -1)
...
}
EOF
igawk -f test.awk
