First of all - thank you very much for providing the CREATE TABLE and INSERT statements. Those really help!
If you have MySQL version < 8.0.2, then you could find the previous level by joining the...

The || represents an unconditional else of an if block.
Use OR instead.

Anyhow.. in your case i'd suggest a case block..
ext=h
case $ext in
cpp|h|js) echo "Do this" ;;
ph|php|lua) echo "Do...

Your histrionic lead-in to a post bereft of concrete examples suggests that, instead of a genuine technical discussion, your primary goal is the promotion of your automation product. The fact that...

You've been close! Try sed '/NEW/{1d;$d}' file

Well, try this one series of statements " with double spaces" in between // some comments here
sed -r 's/([[:alnum:]]) +([[:alnum:]])/\1 \2/g' file
series of statements " with...

Not a regular expression, nor with sed:
awk '
{
for(i=1; i<=NF; i+=2) {
n=split($i,F,"//")
while(match(F[1],/[^ ] +[^ ]/)) F[1]=substr(F[1],1,RSTART) " " substr(F[1],RSTART+RLENGTH-1)...

First attemptsed -r 's/([[:alnum:]]) ([[:alnum:]])/\1 \2/' file
series of statements " with double spaces" in between // some comments here
(Doesn't work between double quotes.)

"Load average" in top is actually the run queue average length.
Over 1 means on average things are waiting on the cpu, below 1 means on average no-one has to wait. Don't confuse this with %cpu -...

Ports are fields in UDP and TCP packet headers that allow the flow to be divided on a host to 65K different apps. For instance tcp cpnnections could be made from 63K different apps on one host to...

The hallmarks of Web 2.0 are (1) rounded corners and (2) web apps which can modify a web page's contents without modifying the browser's history (so you cannot bookmark where you are or share a...

seq 0 25 100000You may do this too, but it's gonna take a while:
i=0; while [ $i -le 100000 ]; do echo $i; i=`expr $i + 25`; done

I personally feel that CSS frameworks are a bad idea.

If you stick with regular CSS, you are using the lowest common denominator and will be 100% compatible with anyone, can go anywhere. With the...

Hi, would like to share a complete reference about Debian GNU/Linux.
TBH, i've never seen a complete reference book like this one here ...

Why this is needed in C goes to the heart of how C compiles and links.

Including <stdio.h> tells the compiler that "somewhere, there exists a function named fgets, which takes arguments of char *,...

You would need to properly quote the characters on the command line and put double quotes around variable references inside the script..

$ cat script
echo "$3"
$ ./script foo bar '!@#.:;_'\'\" ...

The new code detection algorithm is not live yet... so it would not influence anything.

Dropping the font button would be a great relief.

The mtab is usually /etc/mtab. The device is a c character not a b raw device. If there is no parallel raw device, it may be that the USB is being mounted raw as a character device, not through a...

Well, we actually got a good handbook for the included OS and are getting it up and running right now, so no need to switch... But thanks a lot anyway!

Further to post #5 , you'd need to read the file line-by-line, then sort the contents of the line. Also lose the "-s" switch to "tr".

cat filename.txt | while read line
do
sorted=`echo...

The real advantage to learning assembly language is a low-level understanding of pointers and memory handling. You'll have a better understanding of the real operation and cost versus someone who...

try "edit" -> "go advanced" and you should be able to change the tilte of your posts!

[user@host ~]# cat input

I'd start with removing blanks before doing anything else. In C/C++ blanks can only serve two functions: to make code easier to read (indentation) or in output (like "printf( " \n");"). Replace in...

"Understanding" isn't so important. At the end of the results, there is a number labeled "GLOPS". It looks like this:
