--init-file file --rcfile file Execute commands from file instead of the standard per- sonal initialization file ~/.bashrc if the shell is interactive (see INVOCATION below). --login Equivalent to -l. --noeditin
--noediting Do not use the GNU readline library to read command lines when the shell is interactive. --noprofile Do not read either the system-wide startup file /etc/profile or any of the personal initialization files ~/.bash_profile, ~/.bash_login, or ~/.profile. By default, bash ...

Bash is an acronym for ‘Bourne-Again SHell’. The Bourne shell is the traditional Unix shell originally written by Stephen Bourne. All of the Bourne shell builtin commands are available in Bash, The rules for evaluation and quoting are taken from thePOSIXspecification for the ‘standard’ Unix...
The following example shows how to search for a string in a specific file and ignore case: sort Command Thesort commandsorts the lines in text files in a specific order, for example, alphabetically or numerically, which facilitates data organizing and analysis. The command is particularly useful...
This example is the same as above; we only replaced the column number k2 with k1 because we wanted to sort the non-numeric Name column alphabetically. Note that the original file remains unchanged. The sorted output is displayed on the console by default. If you want to save the sorted co...

python可以是命令链中的一部分。python不能完全代替bash。python程序可以像UNIX风格那样(从标准输入读取,从标准输出中输出),所以python程序可以实现一些shell命令,例如cat和sort。 Let's build on the problem that was solved earlier in this article. Besides the work already done, let's find out know how ma...
core UNIX utilities. Previously, I used thesortcommand to sort alphabetically. If the command is provided with a-rnflag, it sorts the lines numerically, in descending order. As the Python script prints to standard out, you simply can pipe the command intosortand retrieve the output you want...
