This article mainly introduces in detail the method of judging the existence of files in linux. The sample code in this article is very detailed and has a certain reference value. Interested friends can refer to it.

Linux determines whether the file exists or not

1. Use the ls command to judge

Ls-l / home/admin/test.txt # View the test.txt file information in the / home/admin/ directory. If it does not exist, an error will be reported.

2. Use find to find and judge

Find / home-name "test.txt" # look for the test.txt file in the / home directory and its subdirectories, no output if it does not exist

3. Use shell script to judge

Save as abc.sh and run using sh abc.sh.

# delete if [!-f "/ data/test.txt"] if the file exists; then echo "file does not exist" else echo "file exists" fi
