![]() ![]() ![]() ![]() It can help us to get different date formats from a Unix timestamp: $ find. Though awk can take a filename expression as an input, it uses that expression to read the contents of the files, where we want to do text processing on the names themselves. We need to use the find command to provide awk with the filenames. The output of ls cannot distinguish them well. This is because a filename could contain whitespace, tabs, or even linebreaks. We should note that, when we write shell scripts, we shouldn’t parse the output of ls. We can use the find command to pipe the filenames to awk as input: $ find. This can be used in place of the -nv options of rename and prename. There is no “dry-run” option for awk, however, if we remove the “ | sh“, awk will print all generated mv commands to stdout without executing them. We can pipe awk generated mv commands to the shell to do bulk renaming: awk '.' | sh Please bear in mind that the “.” after the find command denotes the current directory.Īwk is a powerful text-processing utility. In our case, all files with names containing “ backup” are targeted. The -exec argument tells find to execute rename for every matching file found. Log1-backup.xml log1.txt log2-backup.xml log2.txt log3.txt log4.txt Log1-backup.txt log1.txt log2-backup.txt log2.txt log3.txt log4.txt It looks for the first occurrence of txt in each filename, and replaces it with log.Īlternatively, we can use rename with the find command to target specific files: $ ls The rename command is pretty straightforward. log *.txtįile1.log file2.log file3.log file4.log file5.log Now, let’s use the rename command to rename our. This is because there is no “undo” or “restore” option for a bulk renaming operation. It is recommended to always do a dry-run to make sure that the changes are correct. The rename command with “ -nv” options shows the mistake clearly and gives us a chance to correct the command. LogUObjectHash: Compacting FUObjectHashTables data took 0.In this example, when we typed the command line, we had an extra dot in front of the replacement “ log” by mistake.
