Re: [newbie] invoking bash scripts
On Saturday 14 April 2001 18:28, you wrote: I tried ./scriptname and bash reports "No such file or directory". I can ls and it shows scriptname* which should indicate that it is executable and in the current directory. Careful here. Scripts can be confused in the sense that it'll report 'no such file' when in reality it's not looking at your script (which is there) but at the interpreter in the first line, and complaining about that. bash should (and usually is) invoked as '#! /bin/sh' so I'd try that first. Even so, there should be a symlink in /bin that points 'bash' to 'sh' (or vice versa) so that '#! /bin/sh' or '#! /bin/bash' should produce equivalent behavior. cdrom. Many of the commands fail (e.g. echo -n "Where do you work"). Funny, it prints that text even though I'm not working right now :(. 'echo' is a built in for bash, but there is also a command 'echo'. According to the echo manpage, -n just doesn't give a trailing new line. -- David E. Fox Thanks for letting me [EMAIL PROTECTED]change magnetic patterns [EMAIL PROTECTED] on your hard disk. ---

"David E.Fox"
Here is the bash script I am having problems with...It was
copied from the cdrom for "Linux Shells by Example". (The
lines between the strings of ..
are the script in question.)
#!/bin/bash
# Scriptname: nosy
echo -e "Are you happy? \c"
read answer
echo "$answer is the right response."
echo -e "What is your full name? \c"
read first middle last
echo "Hello $first"
echo -n "Where do you work? "
read
echo I guess $REPLY keeps you busy!
#
read -p "Enter your job title: "
echo "I thought you might be an $REPLY."
echo -n "Who are your best friends? "
read -a friends
echo "Say hi to ${friends[2]}."
*
It is mostly the read command that does not work (e.g. the
line 4: read answer does not capture the answer and line 5:
echo "$answer" does not print the answer supplied.
I execute the script by issuing the following: bash nosy.
Here is the version of bash reported by bash - version

Any ideas

[newbie] invoking bash scripts
Is there some option I need to set to invoke a bash script? I have created a script with the #!/bin/bash as the first line and have chmod +x scriptname to make it executable but it will not execute unless I issue the "bash scriptname" command (preceed the scriptname with the command bash). Is this normal? -- Dean Steichen Mandrake 7.1 K-Mail [EMAIL PROTECTED]
Re: [newbie] invoking bash scripts
Hi Dean, Likely your system is set up (properly so) without the current directory in the path. To invoke a shell script named, say, foo.sh, type this: ./foo.sh (Notice the leading dot-slash) and it should run. This indicates that the script is in the current directory: dot represents the current directory, slash is the pathname separator.

Re: [newbie] invoking bash scripts
I tried ./scriptname and bash reports "No such file or directory". I can ls and it shows scriptname* which should indicate that it is executable and in the current directory. btw: I bought the book "LINUX Shells by Example" by Ellie Quigley and have been trying to run some of the scripts from the cdrom. Many of the commands fail (e.g. echo -n "Where do you work"). Any other ideas? Thanks in advance.
