I'm trying to make a simple reminder timer like this:
#/bin/bash
STRING=$(zenity --forms --title="$OPTION" --add-entry="Enter timer duration: (3600s = 60m = 1h)" --add-entry="Remind me about: ")
TIMER=$(echo $STRING | cut -d"|" -f1)
REASON=$(echo $STRING | cut -d"|" -f2)
if [ $TIMER ]
then
if [ $REASON ]
then
zenity --info --title="Confirmation" --text="I will remind you about \"$REASON\"\n in \"$TIMER\""
sleep $TIMER
zenity --info --title="Timer done" --text="It has now been $TIMER\n\nRemember \"$REASON\"\nTimer done at: `date | awk '{ print $4 }'`"
else
zenity --info --timeout 3 --title="$OPTION" --text="You will be reminded in $TIMER"
sleep $TIMER
zenity --info --title="Timer done" --text="It has now been $TIMER\nTimer done at: `date | awk '{ print $4 }'`"
fi
fi
It works fine but the enter key doesn't press OK on --forms. It does on --entry.
How can I make it work on --forms?

I have a some scripts and, when ı was run manually the scripts were run. But
When working in crontab, the format is incorrect.
This is for a new Linux server
awk 'BEGIN{
FS="-"
print "<HTML>""<table border="1" border="3" cellpadding="4" cellspacing="4" bgcolor=lightblue><TH>Firma</TH><TH>Charged Party No</TH><TH>Pcom Status</TH>"
}
{
printf "<TR>"
for(i=1;i<=NF;i++)
printf "<TD>%s</TD>",$i
print "</TR>"
}
END{
print "</TABLE></BODY></HTML>"
}

You don't have a shebang, nor do you have a complete crontab, so I'm guessing at what you're actually doing. I suspect you are trying to call those multiple commands directly from your crontab, which is a terrible idea. Instead, put your multiple calls into a single script and invoke it from cron. eg, do something like:
$ cat > /path/to/script << 'EOF'
#!/bin/sh
: ${f:=/app/ovocontrol/cp_not_found2.txt}
{
echo "To: **********"
echo "Subject: Son 10 Dakikaya ait Toplu SMS CUDB Hata Detayi"
echo "Content-Type: text/html"
echo
printf '<HTML><table border="1" border="3" cellpadding="4" cellspacing="4"'
printf ' bgcolor=lightblue><TH>Firma</TH><TH>Charged Party No</TH><TH>Pcom Status</TH>\n'
awk -F - ' {
printf "<TR>"
for(i=1;i<=NF;i++) printf "<TD>%s</TD>",$i
print "</TR>"
}
' "$f"
printf '</TABLE></BODY></HTML>\n'
} \
| sed -e 's#failure#<font color="red">failure</font>#g' \
-e 's#success#<font color="green">success</font>#g'
| /usr/sbin/sendmail -t
EOF
$ chmod +x /path/to/script
$ printf 'i\n0 * * * * /path/to/script\n.\nw\nq\n' | EDITOR=ed crontab -e
Note that the last command above is not really a great idea, just an attempt to codify the directive to add /path/to/script to your crontab.
I solved problem other way , "awk '!seen[$0]++'" command incorrect my format. the code was actually a short portion of the code. I think crontab has a special settings.
I'm trying to convert a Debian Bash script into a linux Busybox sh script. I'm stuck trying to convert the following command:
read -r -d '' MESSAGE << EOM
Return code: $retn_code
Start of backup: $DATESTART
End of backup: $DATEEND
$(df -h | grep '/share/USB')
EOM
The problem is with the -d option of read that is not available with Busybox. How can I set a variable ($MESSAGE in this case) to a string with multiple lines that includes values from other variables?
The output MESSAGE is going in a log file and in a message sent by sendmail:
echo "RESULTS: $MESSAGE" >> $LOGFILE
sendmail -S smtp.server.com -f "$FROM" "$RECIPIENTS" <<EOF
subject:$SUBJECT
from:$FROM
$MESSAGE
EOF
Simplest answer is not to use read.
MESSAGE=$(cat <<EOM
Return code: $retn_code
Start of backup: $DATESTART
End of backup: $DATEEND
$(df -h | grep '/share/USB')
EOM
)
MESSAGE=$( printf "%s\n%s\n%s\n%s\n" \
"Return code: $retn_code" \
"Start of backup: $DATESTART" \
"End of backup: $DATEEND" \
"$(df -h | grep '/share/USB')" \
)
You don't need a special command in any shell; just a regular assignment.
message="Return code: $retn_code
Start of backup: $DATESTART
End of backup: $DATEEND
$(df -h | grep '/share/USB')

In a shell script I need to know the value of a variable further down in the code, without running through it first.
This pings $IP which is extracted from $VAR below the while loop.
The $VAR is unknown at the time this is extracted (IP=$(echo $VAR | awk '{print $1}'))
Is it possible to read VAR in before the while loop runs?
The code:
#!/bin/sh
TIMEOUT=10
IP=$(echo $VAR | awk '{print $1}')
while [ $TIMEOUT -ne 0 ];do
ping -c 1 -W 1 "$IP" >/dev/null
rc=$?
if [ $rc -eq 0 ];then
TIMEOUT=0
else
TIMEOUT=$(($TIMEOUT - 1))
echo $TIMEOUT
sleep 1
fi
done
# rest of code to run after while loop
VAR="192.168.0.1 t,r 20,e"

problem is tomcat_pid() method returns process ids of all tomcat instances, because of that, the second instance cannot be started. Is there a better method to handle this?
found a workaround, but expecting better solution
using netstat we can find process id via running port number
echo `netstat -tlnp | awk '/:80 */ {split($NF,a,"/"); print a[1]}'`
So i modified the function tomcat_pid() as below
tomcat_pid() {
echo `netstat -tlnp | awk '/:<port> */ {split($NF,a,"/"); print a[1]}'`
}
