You could write a load-prop function that replaces all non-alphanumeric characters in the variable names with underscore like this:


#!/bin/bash
function load-prop {
. <(
awk '
FNR==NR...

Try (not thoroughly tested):
find . -type f |
awk -F\/ '
{PTH = $0
sub (/\/[^/]*$/, _, PTH)
IX = $NF~/^ERROR/?"ERROR":$NF~/^Runtime/?"RUNTM":"OTHER"
CNT[IX...

You said you wanted to "Extract multiple values into corresponding variables". Depending on your shell, this might work:
IFS=, read BN BD BS <<< $(awk '{A[$1]=$NF} END{print A["Build_SvnRev:"],...

With shell builtins
while IFS=": " read key val
do
val=${val%$'\r'}
case $key in
Build_Number) BN=$val;;
Build_SvnRev) BS=$val;;
Build_Date) BD=$val;;
esac
done < file
echo...

Hi, try:

awk '{A[$1]=$NF} END{print A["Build_SvnRev:"], A["Build_Number:"], A["Build_Date:"]}' OFS=, file

You define a variable named prefix. You expand a variable named myprefix. Try:
prefix='myprefix'; echo "chr, aaaaa|bbbbbb" | sed "s/^/$prefix,/"
which produces the output:
myprefix,chr,...

If I correctly understand what you're trying to do (and I am not at all sure that I do), try:
awk '/key2/ || /key3/{print $2,$3; next}1' fileor:
awk '/key[23]/{print $2,$3; next}1' file
As always,...

First consider the following script stored in a file named tester:

var1="""

var2="

Try also
awk '$1 != LAST {printf "%s%s", DL, $1; LAST = $1; DL = RS} {printf ",%s", $2} END {print _}' FS=, file

Hello kchinnam,

Could you please try following.

awk '{Q=$1} #### Assigning $1's value to a variable named Q here.
($1 in A) #### Checking if $1(first field) is already present in...

$ENV{var} is the facility that Perl has to interact with shell environment variables. Another way is to pass them as command line parameters, but in order to do that you have to write more...

One might guess that perl is used frequently on your system and awk is used infrequently. If that is the case, perl will always be in your cache (and will get consistent timings) while after a few...

Maybe you want something like:
awk '
BEGIN { dqsERE = "\"[^\"]*\""
EREs[++nEREs] = " jndiName=" dqsERE
EREs[++nEREs] = " baseQueueName=" dqsERE
EREs[++nEREs] = " name=" dqsERE
for(i = 1; i...

I asked you if it would work, because <factories.*baseQueueName appeared to me, quite a long regex to verify a line. However, if you really need it, grep is not necessary.
perl -nle...

Note that awk statements take the form:
condition {action}
where condition is evaluated for each input line and, if it yields a value of TRUE or a non-zero numeric value or a non-empty string...

In the code I suggested:
awk '
BEGIN { cmd = "sort -t/ -k1.8,1n -k6.5,6n"
}
/<li>/ {print | cmd
next
}
/<\/ul>/ {
close(cmd)
}
1' file.html
the 1 shown in red at the end of the awk code...

You could also try this awk script. It can handle single-quoted strings, double-quoted strings, and unquoted strings terminated by a space or ">". It requires an equal-sign (with optional leading...

The following produces the same result that you posted for MIN_HEAP and MAX_HEAP

MIN_HEAP=$(perl -ne 'print /initialHeapSize[ \x27"=]+(\d+)/' server.xml)
echo $MIN_HEAP

MAX_HEAP=$(perl -ne...

You haven't said what operating system or shell you're using, but for things like this I usually use awk. This seems to do what you want:
#!/bin/ksh
strear='myapp1-ear'

awk -v...

That's the awk process itself. It should not be matched due to the [r] brackets. Are you sure you used above command pipe?

Add a 1 between closing brace and closing quote and post the result.

The quotes around "EOF" are important, they stop this local-side expansion of the $() command substitution eg:

$ hostname -s
MyPC

$ ssh MyServer <<EOF
echo $(hostname -s)
EOF
MyPC

$...

Assuming that neither the path you want to replace nor the replacement path contain any characters that are special in a regular express AND that the path you want to replace is the some number of...

I wonder if this is what you are after.

sed "s|\(^LoadModule jk_module \).*$|\1$newpathA|"
sed "s|\(^JkWorkersFile \).*$|\1$newpathB|"
sed "s|\(^JkLogFile \).*$|\1$newpathC|"

:confused: No. nohup / myscript.sh don't open the file -- your shell does, before anything else is even run. They just use the file you opened for them.

The line v{v=v"\n"$0} translates to: if v has a value assigned then append current line to v

This causes the script to ignore all lines until a "-----BEGIN" line is seen, at which point v is set...
