I've a small project almost finished. In it, I use some .cgi files in which I make communication between a microcontroler and a webserver. The problem is the following:
If I use this code the project works fine:
#!/bin/bash
./moveRight
echo "Status: 204 No Content"
echo "Content-type: text/html"
echo ""
but when I use this code, nothing happens:
#!/bin/bash
echo "Status: 204 No Content"
echo "Content-type: text/plain"
echo ""
mkdir /tmp/stream
raspistill --nopreview -w 640 -h 480 -q 5 -o /tmp/stream/pic.jpg -tl 100 -t 9999999 -th 0:0:0 &
chmod 777 /dev/ttyAMA0
LD_LIBRARY_PATH=/usr/local/lib mjpg_streamer -i "input_file.so -f /tmp/stream -n pic.jpg" -o "output_http.so -p 8080 -w /var/www" &
What I want is to execute those bash commands when the .cgi is called, do you think what can be my problem? Or any workaround for this issue?

I'm trying to take continuous traces which are written to files that are limited by both duration (-G option) and size (-C option). The files are automatically named with the -w option, and finally the files are compressed with the -z gzip option. Altogether what I have is:
tcpdump -i eth0 -w /home/me/pcaps/MyTrace_%Y-%m-%d_%H%M%S.pcap -s 0 -C 100 -G 3600 -Z root -z gzip &
The problem is that with the -C option, the current file count is appended onto the name, so I wind up with files ending in: .pcap2.gz .pcap3.gz .pcap4.gz, etc. I would much prefer to have them end as: _2.pcap.gz _3.pcap.gz _4.pcap.gz, etc.
But if I remove .pcap from the -w option, I wind up with 2.gz 3.gz 4.gz
This could work if I could include options in the "-z" command like -z "gzip -S .pcap.gz" so that gzip itself appends the .pcap or if I could use an alias like pcap_gzip="gzip -S .pcap.gz" and then -z pcap_gzip, but neither option seems to be working, the latter producing this error: compress_savefile:execlp(gzip -S pcap.gz, /home/me/pcaps/MyTrace_2018-08-07_105308_27): No such file or directory
I encountered the same problem today, In CentOS6. I found your problem, but the answer did not work to me.
In fact, it only needs to be adjusted slightly, that is, the absolute path of the saved file name and the name of the script to be executed is written, for example
tcpdump -i em1 ... -s 0 -G 10 -w '/home/Svr01_std_%Y%m%d_%H%M%S.pcap' -Z root -z /home/pcapup2arcive.sh
I found out that although the alias doesn't work, I was able to put the same commands in a script and invoke the script via tcpdump -z.
pcap_gzip.sh:
#!/bin/bash
gzip -S .pcap.gz "$#"
Then:
tcpdump -i eth0 -w /home/me/pcaps/MyTrace_%Y-%m-%d_%H%M%S -s 0 -C 100 -G 3600 -Z root -z pcap_gzip.sh &
I have the script below.
OUTPUT_FOLDER=/home/user/output
LOGFILE=/root/log/test.log
HOST_FILE=/home/user/host_file.txt
mkdir -p $OUTPUT_FOLDER
rm -f $OUTPUT_FOLDER/*
pssh -h $HOST_FILE -o $OUTPUT_FOLDER "cat $LOGFILE | tail -n 100 | grep foo"
When I run this script on its own, it works fine and the $OUTPUT_FOLDER contains the output from the servers in the $HOST_FILE. However, when I ran the script as a cronjob, the $OUTPUT_FOLDER is created, but it's always empty. It's as if the pssh command was never executed.
Why is this? How do I resolve this?
The following is my code in create_tmux.zsh
#!/bin/zsh
SESSIONNAME=$1
echo $SESSIONNAME
tmux has-session -t $SESSIONNAME &> /dev/null
if [ $? != 0 ]
then
tmux new-session -d -s $SESSIONNAME -n emacs
tmux new-window -t $SESSIONNAME:1 -n a
tmux send-keys -t $SESSIONNAME:1 'ssh -Y a#bc.com;$2' C-m
fi
tmux attach -t $SESSIONNAME
It's simple if I run
create_tmux.zsh ab $%^^&av1#
But in this way, it not only shows in the terminal of my password but also recorded in history.
How can I solve this?
Thank you
I have a shell script to do the following things
sudo as a user (johnsmith) and perform few things
Exit from that user and check url status
If status is not equal to 1 , ssh to one more server and execute a
script.
But when I am running it, the lines inside 'ENDBASH' are not getting executed at all.
#!/bin/ksh
echo "Outside ENDBASH ${###*/}"
sudo -u johnssmith bash <<'ENDBASH'
echo "Inside ENDBASH ${###*/}"
#Obtaining the new version file
for file in "${###*/}"
do
if echo "$file" | grep -E "abc_cde_efg"; then
echo "Version found: $file"
else
echo "Version not found"
fi
done
exit
ENDBASH
urlArray=('http://server:port/servicename1/services/servicename1?wsdl' 'http://server:port/servicename2/services/servicename2?wsdl')
status=0
for url in "${urlArray[#]}"
do
result=`curl -s $url`
if (echo $result | grep '<?xml' >/dev/null 2>&1); then
service=$(echo $url | cut -d"/" -f4)
echo "$service is Running"
else
service=$(echo $url | cut -d"/" -f4)
echo "$service is not Running"
status=1
fi
done
if [ $status != 1 ] ; then
ssh -t username#hostname /home/dev_was/test1.sh
fi
You need to explicitly pass the arguments received by your script to the internal script:
sudo -u johnssmith bash -s "$#" <<'ENDBASH'
For the database in my project I have a drop/create script for the database, a script for creating tables and SPs and an Access 2003 .mdb file with some exported values.
To set up the database from scratch I can use my SQL management studio to first run one script, then the other and lastly manually run the sort of tedious import task.
But I would like to do this as automated as possible. Hopefully something like putting the three files in a folder along with a fourth script to execute. Looking something like:
run script "dropcreate.sql"
run script "createtables.sql"
import "values.mdb"
How is this done? I hope to avoid using SSIS and the like. The tricky this is of course the import of data, where I can't seem to find a simple way. It is also important that the files a left as they are and not embedded into anything.

You can run SQL Server Management Studio in SQLCMD mode. In there you can run scripts as follows
:r c:\temp\DropCreate.SQL
:r c:\temp\CreateTables.SQL
Alternately, you can run the whole thing from a batch file using SQLCMD.exe commands.
SQLCMD -S "." -E -i "c:\temp\DropCreate.SQL"
SQLCMD -S "." -E -i "c:\temp\CreateTables.SQL"
Do you have an alternative to SSIS that can import the data for you? Usually to do any kind of transformations and loading you need error handling, lookups, etc that you will have to code yourself unless you use an off-the-shelf product.
You can read a lot about SSIS right here on SO.
We have a similar project (create db, load data, create code). We do all of this inside a Database Project - with Visual Studio Team System Edition 2008 and GDR2.
