While i'm using the following command in unix command prompt everything is working fine,log fiel is creating fine.
ls -l|echo "[`date +%F-%H-%M-%S`] SUCCESS - FILES"|tee -a logger2.log
but using the same thing in side the shell script it is showing error
No such file or directory.
I'm not getting what is the problem here!!
If I read between the lines: you want a list of files, followed by a date and a message?
try:
{ ls -l ; echo "[$(date "+%F-%H-%M-%S")] SUCCESS - FILES" ; } |tee -a logger2.log
That should give you in 'logger2.log' of the current directory the lines
.................... file
.................... file2
(ie the list of all files and dirs in the current dir, EXCEPT those starting with a ".")
[2013-12-26-..-..-..] SUCCESS - FILES
Please note that, if you put nothing in front of the script, it could be started by a different shell than the one you use when testing. It depends what/who does invoke the script : if it is a crontab, it will probably be interpreted by "sh" (or by "bash" in "sh-compatibility" mode)...
Please tell us what the above gives you as output, and how you start the script (by a user, on the prompt? or via a crontab [which one: /etc/crontab ? or a user's crontab? which user?], etc. And what error messages you see.

Very simple script to copy a file
#!/bin/bash
#copy file
mtp-getfile "6" test2.jpg
I set it as executable and run it using
sudo sh ./test.sh
It gives me a file called test2.jpg that has no icon and I cannot open I get a 'Failed to open input stream for file' error
However, if I simply issue the following from the command line
mtp-getfile "6" test2.jpg
It works as expected. What is wrong with my script? I checked and the resulting .jpg file in each case has the same number of bytes. Very strange.
As commented by chepner, your file might have a DOS (Windows) invisible line ending on its name, which would cause an error. To get rid of this unwanted character(s), just create a new blank script on your "nix" system and type the name by hand (not by copying and pasting, to avoid problems), let's say, name it test2.sh.
Then copy all the contents of test.sh to test2.sh (copy and paste) and run test2.sh and see if it works. If it doesn't, try running the following code on the new script, to make sure that there are no unwanted characters on the code itself:
tr -d "\r" < /folder/test2.sh && echo >> /folder/test2.sh
And then try to run script2.sh again to see if it works. Note: the echo >> /folder/test2.sh part of the code above is just to make sure that your new script ends with a newline, which is a Posix standard (and without which some programs may misbehave because they expect the file to end with a newline).
Apparently it was a permissions issue.
I only had to do a sudu chown test2.jpg
I'm trying to use a CGI script to run a find and replace command on a specific text file.
I currently have a CGI script (foo.sh) which then executes a non-CGI shell script (bar.sh). In the non-CGI shell script (bar.sh), I'm able to perform a number of simple bash commands such as wget, mkdir and cd, and I'm also able to execute a .js file with the standard dot-slash bash syntax.
However, I can't get any find and replace commands to work when executed with CGI. I've tried sed, awk and perl, all of which work perfectly when used either directly on the command line or if I execute bar.sh from the command line. But once I try to execute the CGI script from the browser, the find and replace commands no longer work.
The syntax I've tried is below. Any suggestions appreciated.
sed -i 's/foo/bar/g' text.txt
{ rm text.txt && awk '{gsub("foo", "bar", $0); print}' > text.txt; } < text.txt
perl -p -i -e 's/foo/bar/g' text.txt
just a few thoughts:
if run by the web server, the script will probably be executed as a different user which could lead to permission-related problems.
maybe the awk/sed etc. commands are not in the path used by the web server process (try to use an absolute path here as well)
is there anything in the web server's error log?
Thanks for the input Michael, and sorry for the late response. You were correct in that it was a permissions issue caused by the fact that the CGI script runs not as me but as the "www-data" user.
The problem occurred because that user didn't have write privileges to execute a sed find and replace command on the target folder (in this case a directory within /usr/share/).
I changed permissions on the target folder to full read/write everyone, and now the script runs successfully.
Thanks again.
Given this (among more...):
compile_coffee() {
echo "Compile COFFEESCRIPT files..."
i=0
for folder in ${COFFEE_FOLDER[*]}
do
for file in $folder/*.coffee
do
file_name=$(echo "$file" | awk -F "/" '{print $NF}' | awk -F "." '{print $1}')
file_destination_path=${COFFEE_DESTINATION_FOLDER[${i}]}
file_destination="$file_destination_path/$file_name.js"
if [ -f $file_path ]; then
echo "+ $file -> $file_destination"
$COFFEE_CMD $COFFEE_PARAMS $file > $file_destination #FAIL
#$COFFEE_CMD $COFFEE_PARAMS $file > testfile
fi
done
i=$i+1
done
echo "done!"
compress_javascript
}
And just to clarify, everything except the #FAIL line works flawessly, if I'm doing something wrong just tell me, the problem I have is:
the line executes and does what it have to do, but dont write the file that I put in "file_destination".
if a delete a folder in that route (it's relative to this script, see below), bash throws and error saying that the folder do not exist.
If I make the folder again, no errors, but no file either.
If I change the $file_destination to "testfile", it create the file with correct contents.
The $file_destination path its ok -as you can see, my script echoes it-
if I echo the entire line, copy the exact command with params and execute it onto a shell in the same directory the script is, it
works.
I don't know what is wrong with this, been wondering for two hours...
Script output (real paths):
(alpha)[pyron#vps herobrine]$ ./deploy.sh compile && ls -l database/static/js/
===============================
=== Compile ===
Compile COFFEESCRIPT files...
+ ./database/static/coffee/test.coffee -> ./database/static/js/test.js
done!
Linking static files to django staticfiles folder... done!
total 0
Complete command:
coffee --compile --print ./database/static/coffee/test.coffee > ./database/static/js/test.js
What am I missing?
EDIT I've made some progression through this.
In the shell, If I deactivate the python virtualenv the script works, but If I call deactivate from the script it says command not found.
Assuming destination files have no characters as spaces in their names, directories exist etc. I'd try adding 2>&1 e.g.
$COFFEE_CMD $COFFEE_PARAMS $file > testfile 2>&1
compilers may put desired output and/or compilation messages on stderr instead of stdout. You may also want to put full path to coffee , e.g. /usr/bin/coffee instead of just compiler name.
Found that the problem wasn't the bash script itself. A few lines later the deploy script perform the collectstatic method from django. Noticed that until that line the files were there, I started reading that the collecstatic have a cache system. A very weird one IMO, since I have to delete all the static files and start from scratch to have the script working.
So... the problem wasn't the bash script but the django cache system. Im not givin' reputation to me anyways.
The full deploy script is here: https://github.com/pyronhell/deploy-script-boilerplate and everyone is welcome if you can improve it.
Cheers.
So KDE's clipboard manager - klipper - allows one to write a script to be applied to clipboard contents matching regexp. Say, I want klipper to download an image through bash script.
Here's a klipper QRegExp:
^http://.*\.(png|svg|gif|jpg|jpeg)
I know that this regexp works - klipper notifies me every time I copy image URL to clipboard. Then, here's a bash script
#!/bin/bash
# let's name it clip.bash
name=`basename $1`
curl -o ~/Downloads/$name $1
I put this script to the PATH (I tried to feed this script with a image URL my self - it works), and finally I specify an action the following way:
clip.bash \%s
everything's fine and taken care about - but it doesn't work!
So my question is: "how to make klipper download an image through the bash script?"
First thoughts:
Are you sure about the backslash before the '%'? I haven't access to KDE right now, but I'm not sure you need it.
Are you sure that klipper "sees" your change to the PATH variable? You could try to use absolute path (something like "/home/../clip.bash")
If those don't work, you can try to log some debug info from your script. For example:
#!/bin/bash
name=`basename $1`
echo "curl -o ~/Downloads/$name $1" 1>&2
Run
tail ~/.xsession-errors
to see what command your script have just tried to execute.
I am trying to create a directory based on a variable entered by a user and then save files there.
I thought this would be simple enough for me but I get an error message "No such file or directory" when I try to save there.
When I hit "ls" it lists the directory with a "?" after it.
I am working with an .sh script on a Mac terminal.
Relevant code:
#get user input
echo "enter the collection number"
read COLLECTION
#create the directory
mkdir "$COLLECTION"dir
#calculate a checksum and save it to the above directory
sudo openssl md5 /dev/disk1 > "$COLLECTION"dir/md5.txt
--
Check you script to see if you have DOS style line endings (\r\n). You can safely run dos2unix on the script if you aren't sure.
The ? you see in the file name may actually be the carriage return at the end of the line (since Bash doesn't treat that as whitespace).
So "$COLLECTION"dir/ doesn't exist; "$COLLECTION"dir\r/ does.
Edit:
Vi usually does a good job showing you what those special characters are.
ls | vi -
The only piece of this code likely to give you a "No such file or directory" error is the last line. Does /dev/disk1 exist on your machine?
I use mkdir -p when I get that error ;)
