touch 'file_"name'
touch 'file_`name'

Brilliant. Seems like I'll have to take a look at awk. Thanks.

EDIT: OK, seems like you can make it with grep also ... but what's the role of UNIX95 variable?
For my current level, I'll just...

One more solutions...

Show your updated code please.

The warning is a warning. If you know why it's there and what you're doing, you can ignore it.

It's saying -fpermissive might allow you to follow that suggestion but it might not be a good idea. ...

You are forcing a conversion from a class member to a function call. Class members have this, function calls don't. So it crashes.

If you make the member function static, you'll be able to call...

#!/bin/bash
string1="A\nB\nC D E\nFG\nH"
OLDIFS="$IFS"
IFS="
"
set -- `echo -e "$string1"`
IFS="${OLDIFS}"

echo $1
echo $2
echo...

Check out the updated code ;)

Try:perl -ln0e 'while(/<td class="contentheading" width="100%">\n(.*)/g){$x=$1;$x=~s/\t//g;$x=~s/<\/td>//;print $x}' file

Perhaps like: ${@:3:5}

Well, you'll need a way to communicate with the original process when an extra one is run, so it can check if it's first and if not, just send a message to the first and quit.

Message queues might...

echo '1A23abn' | sed -n '/^[0-9]\{3\}/p'

head -3 filename

Have a read of this:

Man Page for head (POSIX Section 1) - The UNIX and Linux Forums (https://www.unix.com/man-page/POSIX/1/head/)

sed '4,$d' filename

It depends how many dots your string has, and whether you want to keep only the last portion, or delete only the first portion.

i.e.

echo hello.all | sed "s/.*\.//"
all

echo...

Great!

Until you get a .mpeg file :D

or ;)
# echo "hello.all" | grep -ow "..."
all

But 90% of people will have no idea what this thing does, while seeing "basename /some/path" you can at least guess. And when you want to be sure you just do "man basename" and everything is clear....

SDL_mixer is an additional thing to install. Try searching your package manager or see here (http://www.libsdl.org/projects/SDL_mixer/).
