Questions related to if in awk context and if without awk context
I wrote this code, questions follow
Question 1 - how would I write this better so that my commands are executed under the else statement instead of getting a fatal error when $input is not a file in the Directory?
Question 2 - how would I represent this if statement outside this script and not within an awk command? When using if [ $input == echo$(ls) ] or if [[ $input == echo$(ls) ]]
where $input is a file name in the Directory I get a "too many arguments" and false return or just a false return respectively.
I know that this is a relative question but can someone give me an idea of what would be considered a high number of context switches?
I am running vmstat and show a cs value of between 5000 and 6000 on a 4 processor system. How can I deduce if this number is high or not?

If suppose a middle level interrupt is being serviced and a high priority interrupts comes in then in that case what all process will take place.
The interrupt context switch will happen. But where will the interrupt context be saved?

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
