md5sum/shasum #️⃣
Checks/computes MD5/SHA checksum of files.
Compute MD5 checksum md5sum
md5sum ~/.bashrc ~/.zshrc ~/.profile
fc4231f666b25990eefc1c51917d7bb1 /home/babak/.bashrc 6688207953bbd9d20d487a9509a6c297 /home/babak/.zshrc 43f7dc02e7bfb5d40703b5cb94e274ce /home/babak/.profile
Compute SHA1 checksum shasum
shasum ~/.bashrc ~/.zshrc ~/.profile
499460ce753fa4b02cbb8c7e0cb61b1a9583bcd9 /home/babak/.bashrc 2f195c1d8c86cf34e4bdbd947e76fc9cb0bc900e /home/babak/.zshrc 63d1a74119f9a8a84fd930ed8341395e9ab867f0 /home/babak/.profile
Compute other SHA checksums -a
shasum -a 256 ~/.bashrc ~/.zshrc ~/.profile

Create checksums file for later checks
shasum ~/.bashrc ~/.zshrc ~/.profile > SHA1SUMS
md5sum ~/.bashrc ~/.zshrc ~/.profile > MD5SUMS
Check checksums --check
shasum --check SHA1SUMS
md5sum --check MD5SUMS
/home/babak/.bashrc: OK /home/babak/.zshrc: OK /home/babak/.profile: OK
