I've been trying to get this function to work without returning errors, but so far I'm unable to figure out what the problems is. I'm using $(report_home_space) to insert the contents of the functions on a small bit of hmtl but keep getting the error: report_home_space: command not found on line 30.
report_home_space () {
cat <<- _EOF_
<H2>Home Space Utilization</H2>
<PRE>$(du -sh /home/*)</PRE>
_EOF_
}
I'm new to shell scripting, but I can't not find anything wrong with the syntax of the function, and the spelling seems correct. Thanks in advance.
Full script is:
#!/bin/bash
# Program to output a system information page
TITLE="System Information Report For $HOSTNAME"
CURRENT_TIME=$(date +"%x %r %z")
TIMESTAMP="Generated $CURRENT_TIME, by $USER"
report_uptime () {
cat <<- _EOF_
<H2>system Uptime</H2>
<PRE>$(uptime)</PRE>
_EOF_
}
report_disk_space () {
cat <<- _EOF_
<H2>Disk Space Ulitilizatoin</H2>
<PRE>$(df -h)</PRE>
_EOF_
}
report_home_space () {
cat <<- _EOF_
<H2>Home Space Utilization</H2>
<PRE>$(du -sh /home/*)</PRE>
_EOF_
}
cat << _EOF_
<HTML>
<HEAD>
<TITLE>$TITLE</TITLE>
<BODY>
<H1>$TITLE</H1>
<P>$TIMESTAMP</P>
$(report_uptime)
$(report_disk_space)
$(report_home_space)

BTW, your script works fine. Did you by any chance type it up in a Windows environment before uploading to a UNIX env? Try running:
What this does is change line endings from from Windows to unix format. i.e. it strips \r (CR) from line endings to change them from \r\n (CR+LF) to \n (LF).
Also, on a HTML note, you're missing a closing tag for "< HEAD >" after your title tags.
