Shell Scripting

Question

I'm trying to run my .sh file but when I try to execute it it doesn't work. I did echo '#!/bin/bash' > cadetkpgm.sh in order for the .sh file to be executable but when I use ./cadetkpgm.sh or bash cadetkpgm.sh to run the file t it doesn't work... any ideas?

What's the error message? It probably tells you exactly what the problem is ;-) — janos, Feb 25 '14 at 19:04
It looks like the line 1 of `cadetkpgm2.sh` is `cadetkpgm2.sh`. Check what's inside the file using `cat cadetkpgm2.sh`, because I think it's not what you think it is. After you fix the content of the file, `bash cadetkpgm2.sh` will run it. You can make it executable with `chmod u+x cadetkpgm2.sh`. — janos, Feb 25 '14 at 19:09
i placed the shebang on the top by useing the echo '#!/bin/bash' > cadetkpgm.sh — Kerven Cadet, Feb 25 '14 at 19:14
I am little bit confused. What is your file name `cadetkpgm.sh`or `cadetkpgm2.sh`? — g_p, Feb 25 '14 at 19:24
And what is the purpose of this first one. Pls provide a little bit more detail. — g_p, Feb 25 '14 at 19:36
`echo '#!/bin/bash' > cadetkpgm.sh` would overwrite your file to just contain `#!/bin/bash` — Dan, Feb 25 '14 at 20:28

#!/bin/bash does not turn your shell script into an executable.

It only makes sure that it will be interpreted by bash for which you give the location - once you have made it executable by chmod u+x SCRIPTNAME.

Let me explain again: cadetkpgm.sh is not a command, unless you have made it executable.

im required to place that into the .sh file. when I try to run it it gives me this error: ./cadetkpgm2.sh: line 1: cadetkpgm2.sh: command not found. – Kerven Cadet Feb 25 '14 at 19:10

and it has to be on your $PATH as well. – Panther Feb 25 '14 at 20:20
