Hi, try:
awk -F, '$1=="" || $3=="" || $8=="" {print>f; next}1' f=test_exc file.out > filenew.out

Again you probably want to trim $26 before doing a compare so:

nawk -F, '
FNR==NR{C[$2]=$1;next}
{sub(/ *$/,"",$26);if($26==C[$2])$26=C[$26]}1' OFS=, reffile mainfile.csv

Try this:

awk -F, 'FNR==NR{C[$2]=$1;next}{$26=C[$26]}1' OFS=, reffile mainfile.csv

First I should note that setting FS to a regex like this is a GNU awk feature. Most other versions of awk can't do that.

For a really complicated line like this, you can change FS on the fly and...

Yes. Just change your FS as FS="[ |:|@||\t+]";



Usually you can avoid piping a grep result into aw by just using the awk condition filtering like in /string to capture/{... awk processing...}

You're mistaken. You can indeed just test the result of a command subsitution or any shell expansion by itself. [[ -n "..." ]] and [[ "..." ]] are synonymous.

VAR1="hostname63uf.group"
if [[ "$var1" =~ /63u/ ]]

SUB2="23421"

then

2 things are wrong -
1. You are missing a double quote in your expression (echo $VAR1")
2. Your test expression can't just be the output of the grep command - you need to perform some kind of test...

"Do Maintenance")

Why are you still selecting based on $X though? Use $REPLY, which will be the number typed in, so you can have cases 1) ;; 2) ;; instead of cramming entire titles into them,...

I used IFS="|" so you could have long option names with spaces in there.

You'll probably want to check REPLY instead of X for the value select reads, though! That'll be the number the user...

Here's an example using select and the argument array to easily switch between many menus. The same code prints all the menus and reads all the replies using the select builtin.

We use the the $1...

1) create a file with "0" in /tmp/size.txt

for fs in `df -k| grep -v "^Filesystem|devices|ctfs|proc|mnttab|swap|objfs|sharefs|fd|odm" | awk '{print $1}'`; do
x="`df -kl | grep $fs | awk '{ print...

Or alternatively, use plain shell without pipes, e.g.
START=2; STOP=7
linenr=0
while IFS=: read x y z ; do
linenr=$((linenr+1));
[ $linenr -ge $START ] || continue
[ $linenr -le $STOP ]...

I cut/pasted the code in your post and it seems fine to me; I'm not getting an error. Can you past in your whole script, there is likely a typo somewhere in it.

An explanation:

The STOP and...

In your original example the variable i was assigned the whole record (e.g. val1:env1:opt1). In the code that zaxxon suggested, the components val1 env1 opt1 were broken out and assigned to...

If I got it right, you can break it down altering IFS:

OLDIFS=$IFS
IFS=":"

while read A B C; do
do someting here with $A or $B or $C
done < infile

IFS=$OLDIFS

If you run this script from a terminal, you should be able to read < /dev/tty to use the terminal directly without bothering stdin. /dev/tty is a special device which opens whatever device is your...

It's not the "if" condition, its the "read -p" (which was not mentioned in your previous post). It's in backticks so it still functions within the "echo" line.
There is only one STDIN channel and...

Given that awk script doesn't even have 7 lines, I'm not sure what to tell you about the syntax error, but if you want a standard deviation for each column, you're going to need to loop over each...

try this
xargs -i sh -c './shscript {}' < parameters.txt

There is no difference between having them in a file and having them in your file, ergo there is a typo.

Methyl identified it above for you.
