could somebody please help me find the problem with this code? getting this error "mv: cannot stat '~Desktop/RecyclingBin/testtest' : No such file or directory. It does exist and it is in the location ~Desktop/RecyclingBin/testtest
fileName=$1
fileLocation='cat ~/Desktop/RecyclingBin/logs/$fileName
if [ -z "$1" ]
then
echo "please enter a valid filename"
else
echo "do you want to restore?"
read ans
if [ "$ans" =="y" ]
then
mv "~/Desktop/RecyclingBin/$fileName" "$fileLocation"
fi
fi
The quotes prevent expansion of ~. Put it outside the quotes:
mv ~/Desktop/RecyclingBin/"$fileName" "$fileLocation"

You just have to get the input for the do loop right:
#!/bin/bash
if [ -f "$1" ]
then
for user in $(cat "$1")
do
useradd "$user"
done
else
echo "input is not a file"
fi
Remarks: this works for reading out a file word-by-word and I tried to keep your structure.
For reading out files line by line this is an elegant way: https://stackoverflow.com/a/4642213/2819581

Use a for loop instead of getting the filenames from the user.
#!/bin/bash
for file in /etc/*; do
if [ -f "$file" ]
then
echo "$file is a regular file"
elif [ -d "$file" ]
then
echo "$file is a directory"
else
echo "$file is something else"
fi
done
Don't forget to quote variables, in case the value contains a space. And there are other possibilities than just files and directories.

Escape your variables. Read about it here.

Why should there be spaces around '[' and ']' in Bash?

Closed 6 years ago.
I am trying to make a simple script that would move junk files into a bin like directory.
The code i wrote is here:
echo "Which file/s you want to delete?"
read fileName
if [ -d "/home/user/.waste"]
then
#moves the file to .waste
mv $fileName /home/user/.waste
echo "File deleted."
else
#creates the directory
mkdir /home/user/.waste
mv $fileName /home/user/.waste
echo "waste bin created and file deleted."
fi
When i run the script while having the directory it keeps going to the else option and does not recognize the value i entered in the if statement.
I suspect the test is incorrect (needs a space before the closing bracket).
if [ -d "DIR" ].
#!/bin/bash
WASTE_DIR="/home/user/.waste"
echo "Which file/s you want to delete?"
read fileName
if [ ! -f "$fileName" ]
then
echo "Unable to find file "$fileName"
fi
if [ -d "$WASTE_DIR" ]
then
mv "$fileName" "$WASTE_DIR"
echo "File moved to waste"
else
mkdir -p "$WASTE_DIR"
mv "$fileName" "$WASTE_DIR"
echo "$WASTE_DIR created and file moved"
fi

How do I tell if a file does not exist in Bash?

Closed 4 years ago.
i made a linux script which receives as first argument a path to a directory. I don't know the path. And i want to check if "file.txt" exists at that certain path . For example :
if [ -e $1/file.txt ];then
echo HAHA
fi
if [[ -e "$1/file.txt" ]]; then
echo "It exists"
fi
