Q&A for How to Find a File in Linux

The 'ls' command lists all files in the current directory you are working in. To find out what directory you are working in, type 'pwd' (stands for "print working directory").

You have to used tail command to display the last lines of a file, the command used is, "tail -n filename." To display last 10 lines the command will be: tail -10 filename.

You can try searching for a file extension, or checking places where files are commonly saved, such as your home directory. If it's a text file, you can try using a recursive grep search ('grep -R') with text that you remember from the file as search criteria.

Using `ls` you can find files that contain the specific letters you specify. For example, you want to find all files in the directory that contain "abc" in their name, type " ls -d *abc* " It will list all matching files. But if you want to find files more recursively, type " find | grep -r "abc" " You may remove the "-r" if you don't want to search too deep.

To find the file, type: `find ~/ -iname "test.sh" ` This will print the path to your file, if it exists. If you didn't find the file you are looking for, try searching in other places. To make a file and print hello, type this: ` touch test.sh ; echo "hello" > test.sh `
