advanced patterns with parameter expansion in Bash scripts while handling spaces
I've encountered a strange issue with I'm stuck trying to I'm upgrading from an older version and I'm sure I'm missing something obvious here, but I'm working with an scenario with parameter expansion in my Bash script when dealing with filenames that contain spaces. I'm trying to read a list of filenames from a file and then process each one with a command. However, when a filename has spaces, the command fails because the parameter expansion doesn't seem to handle it correctly. Here’s a simplified version of my script: ```bash #!/bin/bash while IFS= read -r file; do echo "Processing file: $file" cp "$file" /destination/directory/ done < file_list.txt ``` The `file_list.txt` contains the following entries: ``` file with spaces.txt another_file.txt yet another file.txt ``` When I run the script, I get the following behavior for files containing spaces: ``` cp: want to stat 'file': No such file or directory ``` I've tried quoting the variable in the `cp` command as `cp "$file"`, but it still fails. It seems like the quotes aren’t being recognized correctly, leading to the command treating spaces as argument separators. I've also checked the `IFS` variable and ensured it’s set to read the entire line. I thought about using `find` to handle the files, but I prefer sticking to a simpler loop. Is there something I'm missing here? Any advice on how to properly handle filenames with spaces in a Bash script would be greatly appreciated! I'm working on a CLI tool that needs to handle this. What am I doing wrong? The stack includes Bash and several other technologies. Thanks, I really appreciate it! This is my first time working with Bash stable.
