While the ctime field sounds similar to crtime, it does not tell us the file creation date. We can see that we created the file on âFri Dec 17 06:17:09 2021â.

Inode: 5118705 Type: regular Mode: 0644 Flags: 0x80000 Files in Linux have 3 types of timestamps: atime (access), mtime (modify) and ctime (change). The syntax is debugfs -R âstat â /dev/sdX where inode is our file inode, and /dev/sdX is the filesystem of the file: $ sudo debugfs -R 'stat ' /dev/sda2 Now, we can pass this information to the debugfs command. Stack Exchange network consists of 183 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. For this, we can use the âformat flag with %w as its value:įilesystem 1K-blocks Used Available Use% Mounted on We can also instruct stat only to give us the required data, which is the file creation date in our case. Size: 15 Blocks: 8 IO Block: 4096 regular file Now, letâs modify the file and check that only the âModifyâ field changes, as it indicates the last modification time: $ echo "Modified" > file Size: 6 Blocks: 8 IO Block: 4096 regular fileĪccess: (0644/-rw-r-r-) Uid: ( 1000/baeldung) Gid: ( 1000/baeldung)Īs we can see, the creation date is shown in the âBirthâ field. Logically, you use the strptime () function from POSIX. ![]() Generating the time corresponding to a given date/time value is rather less easy. Generating the current time in Perl is rather easy: perl -e print time, 'n'. Letâs create a file and check its creation time: $ date echo "Hello" > file A Unix time stamp is the number of seconds since that time - not accounting for leap seconds. etc/ftpusers /etc/hosts /etc/inet/ipnodes /etc/netmasks /etc/vsftpd.The easiest way to get the file creation date is with the stat command.
