How do I exclude what my script is doing and only have echo's print?
For instance, i am taring a directory and I don't want every file it tar's to echo.. only the echo command.
#! /bin/bash
clear
echo "Compressing the files"
cd ~/LegendaryXeo/html/
tar --exclude=".git" -cvf site.tar *
mv site.tar ~/LegendaryXeo/work/
cd ~/LegendaryXeo/work/
clear
echo "Extracting the site"
tar -xvf site.tar
echo "Deleting Tar"
cd ~/LegendaryXeo/work/
rm -f site.tar
clear
echo "Copying files to server"
scp -r ~/LegendaryXeo/work/* user#site.com:~/../../domains/
Redirect the output of tar to /dev/null:
tar [your options] [files] &> /dev/null
Any echo command you have in your script will still output to the screen.

I'm stuck with this script and would like some help on the same!
I want to make a folder called "upload" which will contain a script that copies a .jar file from there to multiple directories (See below)
/home/minecraft/multicraft/servers/EUSim1
/home/minecraft/multicraft/servers/EUSim2
/home/minecraft/multicraft/servers/EUSim3
and so on.
A Quick Script, for reference:
script
#!/bin/bash
inputfile=$1
for var in "$#"
do
if [[ $2 == $3 ]];then
exit 1
fi
cp -v $inputfile $2
shift
done
Command
./script simple.jar \
/home/minecraft/multicraft/servers/EUSim1/simple.jar \
/home/minecraft/multicraft/servers/EUSim2/simple.jar \
/home/minecraft/multicraft/servers/EUSim3/simple.jar \
Output
'simple.jar' -> '/home/minecraft/multicraft/servers/EUSim1/simple.jar'
'simple.jar' -> '/home/minecraft/multicraft/servers/EUSim2/simple.jar'
'simple.jar' -> '/home/minecraft/multicraft/servers/EUSim3/simple.jar'
This is a simple script. you can do little tweaks and add --prefix or make the script read the input from a file.
(or)
use cp with xargs:
echo dir1 dir2 dir3 | xargs -n 1 cp file
Very simple script:
How to use it
touch simpleScript.sh
vim simpleScript.sh
Copy/Paste the line below
Update TRX_SOURCE_PATH, DEST_PATH, DEST_PATH1, DEST_PATH2
Save
chmod +x ./simpleScript.sh
#!/bin/bash
TRX_SOURCE_PATH='/Path/Test.pdf'
DEST_PATH='/Path/Test'
DEST_PATH1='/Path/Test1'
DEST_PATH2='/Path/Test2'
echo "Starting copy"
echo "Destination:" $DEST_PATH
cp $TRX_SOURCE_PATH $DEST_PATH
echo "copy done for folder:" $DEST_PATH
echo "Destination:" $DEST_PATH1
cp $TRX_SOURCE_PATH $DEST_PATH1
echo "copy done for folder:" $DEST_PATH1
echo "Destination:" $DEST_PATH2
cp $TRX_SOURCE_PATH $DEST_PATH2
echo "copy done for folder:" $DEST_PATH2
echo "All Copy done"
Hope this script helps you .
As many others have done, I want to create a repo to store my dotfile customizations. Instead of doing ln -s manually, I am using the following script to set things up.
#!/bin/bash
set -e
DIR="$HOME/Documents/Dotfiles"
OLDDIR="$HOME/Documents/Other\ Files/Dotfiles_old"
FILES=($HOME/.bash_profile)
echo "Creating $OLDDIR for backup of any existing dotfiles in ~"
mkdir -p "$OLDDIR"
echo "…done"
echo "Changing to the $DIR directory"
cd "$DIR"
echo "…done"
for FILE in "${FILES[#]}"; do
echo "Backup dotfile $FILE from ~/ to $OLDDIR"
cp -L "$HOME/$FILE" "$OLDDIR"
done
for FILE in "${FILES[#]}"; do
echo "copy $FILE from ~ to $DIR."
cp -L "$HOME/$FILE $DIR/"
echo "Creating symlink to $FILE from ~ to $DIR."
ln -sfn "$DIR/$FILE" "$HOME/$FILE";
done
shellcheck source "$HOME/.bash_profile"
When I run this, cp fails because it thinks that .bash_profile isn't there, which obviously isn't the case:
I think my path to the files may be incorrect, although shellcheck reports nothing. What am I forgetting here?
UPDATE: Made another run at this - minus the cp. The one thing I am still unsure of is the use of exit, in particular since I'm already using -e to check for errors.
Shellcheck and bash -n return 0.
#!/bin/bash
set -e
function makeFiles() {
touch .bash_profile \
touch .gitconfig \
touch .gitignore_global
}
function makeLinks() {
ln -sfn ~/Documents/Dotfiles/.bash_profile ~/.bash_profile \
ln -sfn ~/Documents/Dotfiles/.gitconfig ~/.gitconfig \
ln -sfn ~/Documents/Dotfiles/.gitignore_global ~/.gitignore_global \
source ~/.bash_profile
}
read -rp "This may overwrite existing files. Are you sure? (y/n) " -n 1;
echo "";
if [[ $REPLY =~ ^[Yy]$ ]]; then
makeFiles && makeLinks
fi;
Sigh, ln decides that .bash_profile needs to be a directory for some crazy reason.
You're building the path of the dotfile incorrectly - $FILE already contains the full path of the dotfile, and there's no need to prepend $HOME again. Try with this cp command:
cp -L "$FILE $DIR/"
My script skills are really limited so I wonder if someone here could help me. I would like to download 2 files, run gunzip, run a command called tv_merge and then gzip the new file. Here's what I Would like to be run from a script.
I would like to download two files (.gz) with wget:
wget -O /some/where/file1.gz http://some.url.com/data/
wget -O /some/where/file2.gz http://some.url.com/data/
Then gunzip the 2 files:
gunzip /some/where/file1.gz
gunzip /some/where/file2.gz
After that run a command called Tv_merge:
tv_merge -i /some/where/file1 -m /some/where/file2 -o newmaster.xml
After tv_merge. I would like to gzip the file:
gzip newmaster.xml
I would like to run all these commands in that order from a script, and I would like to put that to be run let's see every 8h like a crontab.
I'm assuming that file names are static. with provided information this should get you going.
#!/bin/bash
echo "Downloading first file"
wget -O /some/where/file1.gz http://some.url.com/data/
echo "First Download Completed"
echo "Downloading Second file"
wget -O /some/where/file2.gz http://some.url.com/data/
echo "Second Download Completed"
gunzip /some/where/file1.gz
gunzip /some/where/file2.gz
echo "Running tv_merge"
tv_merge -i /some/where/file1 -m /some/where/file2 -o newmaster.xml
gzip -c newmaster.xml > /some/where/newmaster.xml.gz
echo "newmaster.xml.gz is ready at /some/where/newmaster.xml.gz"
Save this to a file for example script.sh then chmod +x script.sh and you can run it with bash script.sh.
I cannot seem to get my bash script to work, i want to pipe the output from the gunzip command to another command but it is not working, can anyone help me?
The gunzip command outputs a tar file that i want to then use the tar command to put back yo the original file.
# let the user choose what they want to Restore
echo -n "Select the file or directory you want to Restore"
read Chosendata
echo -e "Starting Restore"
# unziping files
gunzip ${Chosendata} | tar xvf - #Here
# end the restore.
echo -e "Restore complete"
Use gunzip -c.
-c, --stdout write on standard output, keep original files unchanged
Or tar only: tar -xzf ${Chosendata}.
I have a bash script that is getting an accented character appended to some strings that is causing it to fail, and I can't find where or how these characters are getting in there.
Here is some example output:
mv: cannot move â/tmp/myapp.zipâ to â/opt/myserver/myapp/deploys/myapp.1.2.21.zipâ: No such file or directory
ln: failed to create symbolic link â/opt/myserver/myapp/deploys/myapp_beta.zipâ: No such file or directory
cp: cannot stat â/opt/myserver/myapp/deploys/myapp_beta.zipâ: No such file or directory
the invalid character is the â.
The script is below:

can anyone possibly see the issue or suggest a way I can go about finding where the issue is?
Those â characters are just mangled smart quotes printed from your shell. Your shell is probably outputting UTF-8, but your terminal is reading ISO-8859-1. Note that â is the rendering of a UTF-8 encoded smart quote ‘ in ISO-8859-1, with two nonprintable characters following the â. Most modern terminal emulators come with an option to enable UTF-8; see if you can enable that (it will make your life easier).
The problem is in your script, not the funny characters.
Try opening the script in another text editor like Notepad++ and see if there are any special characters present.
From the command line, type both of these commands. One or more of the files/directories you are expecting to exist, does not exist.
ls /tmp/myapp.zip
ls /opt/myserver/myapp/deploys
The accepted answer explains the problem, thanks #nneonneo. This is what you can do for a quick fix:
A) check your locale settings with:
locale
B) before calling your script or in the top of your bash-script try:
export LANG=en_US.UTF-8
export LC_ALL=C
