I do not really see what this all brings, I think I would prefer the two greps to the awk solutions, because they are easier to understand and thus to maintain. One could go even further and put everything in one awk:
Code:
awk '
NR==2,NR==10 {
if (/error/) {
if(/memory/) {
m=m RS $0
i++
}
else {
o=o RS $0
j++
}
}
}
END{
print i m RS j o
}
' file
This probably would make it more efficient, but one could ask if that is required and the down side is that it is also less simple...

Hi
Maybe you can suggest a nicer way to do the following:
RET_STR=$(echo ${RET} | sed -e 's/0/Object is not mapped/' \
-e 's/1/Operation Internal Error/' \
-e 's/2/Operation Invalid Arguments/' \
-e 's/3/Object is mapped/' \
-e 's/4/Path not found/') (3 Replies)
Hi Guys,
I need to set the value of $7 to zero in case $7 is NULL. I've tried the below command but doesn't work. Any ideas. thanks guys.
MEM=`ps v $PPID| grep -i db2 | grep -v grep| awk '{ if ( $7 ~ " " ) { print 0 } else { print $7}}' `

Hello,
I trying to extract text that is surrounded by xml-tags. I tried this
cat tst.xml | egrep "<SERVER>.*</SERVER>" |sed -e "s/<SERVER>\(.*\)<\/SERVER>/\1/"|tr "|" " "
which works perfect, if the start-tag and the end-tag are in the same line, e.g.:
<tag1>Hello Linux-Users</tag1>

this code below is very useful in calculating mean and quartiles. however, i would really like to translate it to awk without having to write to any external file:

igawk
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
