-bash: ./p4: /bin/ksh^M: bad interpreter: No such file or directory
I keep getting this error and I am not sure why.

Code:
-bash: ./p4: /bin/ksh^M: bad interpreter: No such file or directory


First I run my makefile and this works fine:

Code:
goodmain: main.o
    gcc -o goodmain main.o

main.o: main.c
    gcc -c main.c


Then I want to limit my output so I created this shellscript.

Code:
#!/bin/ksh
goodmain $1 | sed -e '1,/mmxxaa/d'

I run it like this:

Code:
./p4 textfile

I thought $1 meant the second input. This works fine when I run it from the command line. Can anyone spot my issue?

Try:
Code:
cp p4 _p4 && tr -d '\r' < _p4 > p4 && rm _p4

Yes that fixed one problem. Now it can't seem to find my files.

Code:
$ ls -l

What do you get as output from the command:
Code:
ls *o*|od -bc

I assume that by now you're aware that when writing shell scripts you MUST use an editor that uses a single <newline> character as the line terminator on the output it produces (NOT the DOS <carriage-return><newline> character pair).

Yes I know, but no I did not remember. I thought I had my notepad++ set for unix files but it didn't work for some reason.

Code:
$ ls *o*|od -bc

What PATH do you use?
You need to set the path to goodmain in your script, like /path/to/goodmain or by including it in the PATH variable.
