[SOLVED] adding text to file using echo

BW-userx · 10-17-2016, 10:46 AM

I was trying to be lazy about this and just create a bash script right off of the command line then adding what I needed inside of it by doing this. but BASH keeps thinking i am trying to run one I think.
instead of just opening up a text editor and do this, but because BASH is doing what it is doing it raised a question . how do I do this without having to open up a text editor.

add the line #!/bin/bash

Code:

userx@Voided.1 & ~ >>touch playmusic

userx@Voided.1 & ~ >> $echo "#!/bin/bash" > playmusic 
bash: !/bin/bash: event not found
userx@Voided.1 & ~ >> $hi="#!/bin/bash"
bash: !/bin/bash: event not found
userx@Voided.1 & ~ >> $hi="hi"
userx@Voided.1 & ~ >> $echo hi > playmusic
userx@Voided.1 & ~ >> $cat playmusic
hi
userx@Voided.1 & ~ >> $hi="/#!/bin/bash"
bash: !/bin/bash: event not found

userx@Voided.1 & ~ >> $hi="\#!/bin/bash"
bash: !/bin/bash: event not found

do you understand what is going on here? Bash will not allow me to echo its directive into a file.

how do I do this?

It's about the quotes and the exclamation mark:

Escaping characters would be good to know as well:

Code:

echo \#\!/bin/bash > test
cat test
#!/bin/bash

oh I just needed one more escape, and that'd a would have worked too. again more then one way to skin a cat.
as I tried it hitting that wrong one / first time then the other one \ the next time, but only placing in one of them.

if you go back and look you'll see.
