I want to stick all the variables into one variable A=('blah') AA=('blah2') AAA=('blah3') AAB=('blah4') AAC=('blah5') #^^lets pretend theres 100 more of these ^^ #Variable composition #after AAA, is AAB then AAC then AAD etc etc, does that 100 times I want them all placed into this MASTER variable #MASTER=${A}${AA}${AAA} (<-- insert AAB, AAC and 100 more variables here) I obviously don't want to type 100 variables in this expression because there's probably an easier way to do this.

There are many questions on this site on how to escape various elements for sed, but I'm looking for a more general answer. I understand that I might want to escape some characters to avoid shell expansion: Bash : Single quoted [strings] ('') are used to preserve the literal value of each character enclosed within the quotes.

EDIT: they are big

I have a few game servers that that I need to run shell scripts for frequality. I'm trying to figure out how to run these scripts via a webpage on the same server. It's a Ubuntu Dedicated server. The website files are located via /var/www/... The .sh files I need to manually run are located in /home/amservers/.../start.sh . I've looked at other answers and I still can't figure it out. How do locate the files and store it and then run exec()? You could just use the shell_exec() function in PHP: http://php.net/manual/en/function.shell-exec.php shell_exec('sh script.sh'); And if you want to use
