Hi. When you write a script/program in vi Do you include the $ Eg. #!/bin/bash $ echo "Today's date is `date`" or echo "Today's date is `date`" Make your script executable. $chmod +x script I included that. I keep getting a permission denied... why? Thanks!
Hi. When you write a script/program in vi . Do you include the $ Eg. . $ echo "Today's date is `date`" or . echo "Today's date is `date`" . Make your script executable. . $chmod +x script I included that. . I keep getting a permission denied... why? Thanks!
You will need to explain your problem a little better.
1) You are creating a script in vi. I do not understand what you mean by "do you include...".
Scripts are flat ASCII files with shell or program specific commands. Please clarify your question.
2) I assume you mean in the execution of the saved scriptfile... if this is the case, then you will have to change the attribute of the scriptfile to allow for execution. Please see "chmod" for details. If you would like to change the file to executable:
3) Your post indicated that you chmod'd the file, thus the last thing your should check is the PATH variable to make sure that the residing directory is included or execute the file with a preceding "./" ,as in ./scriptfile
Sorry for double, I tried to fix the spacing.. In vi echo "Today's date is `date`" or $ echo "Today's date is `date`" Include the dollar sign or no? “Written as echo "Today's date is `date`" save and quit vi chmod 755 script -gives permission to your script ./script -executes your script” ./filenameDate echo $PATH chmod +x scriptfile or chmod +x scriptName1 I'm still confused.. 8( But I'm keep trying... Thanks
When writing scripts, you do not include the "$" at the beginning of the line, since in a shell, the "$" is actually the command prompt. The $ has a specific meaning within the shell program itself (it is used to reference variables).
Thus, in the example you supplied, vi a file called "myscript.sh". The script program would look similar to the following:
Note the quotes around the echo statement. This is due to the fact that you have an apostrophe within the desired phrase.
Step 2) Save the file and chmod +x myscript.sh
Step 3) ./myscript.sh
or
Step 3a) echo $PATH to see if the directory where "myscript.sh" is included, if not, include it using the following (for a Bourne/Korn shell or equivalent) into your login profile
PATH=$PATH:/newdirectorytoadd
export PATH
for csh users,
set path=($path /newdirectorytoadd)
or
setenv PATH ${PATH}:/newdirectorytoadd
(I'm not a csh power user, so double check this...)
Step 3b) at the command prompt, just execute the myscript.sh file
Don't think I can get much more explicit, I hope this helps.

I tried to include a header named DefineVars- which initializes all the globals- but when I add the line "DefineGlobals" at the begining of another... (2 Replies)
