How to merge multiple files with awk commands in Linux

In Linux, awk commands Merge multiple files. Recently, during the project process, all text files in the specified directory need to be merged and output to a single text file, I finally found a command to merge 1700 text files and the format has not changed. The command is as follows: www.2cto.com 1 awk '{v = FILENAME }! A [v] ++ 1'/tmp/data/pps /*. ips>/tmp/all.ips.txt and above are all in the/tmp/data/pps/directory. the files ending with ips are in txt files. You may wish to help me. In my project, I am using this awk command by yangqijun.
