To sort these arrays, we use printf "%s\n" to print each element on a new line, which is then piped (|) into the sort command. For the numeric array, we use sort -n to ensure numerical sorting. For the string array, a simple sort suffices, as it sorts alphabetically by default....
Conditional operators such as -f must be unquoted to be recognized as primaries.When used with [[, the < and > operators sort lexicographically using the current locale.See the description of the test builtin command (in the section "Shell Builtin Commands" below) for the handling of ...
ment (see Arrays below), the variable's value is not unset (as it is when using =), and new values are appended to the array beginning at one greater than the array's maximum index (for indexed arrays) or added as additional key-value pairs in an associative array. When applied to ...
Bash contains features that appear in other popular shells, and some features that only appear in Bash. Some of the shells that Bash has borrowed concepts from are the Bourne Shell (sh), the Korn Shell (ksh), and the C-shell (cshand its successor,tcsh). The following menu breaks the f...
BASH_ARGC An array variable whose values are the number of param- eters in each frame of the current bash execution call stack. The number of parameters to the current subrou- tine (shell function or script executed with . or source) is at the top of the stack. When a subroutine is ...
Additionally, if you want the output to be sorted alphabetically instead of numerically, you can execute freqL.sh and then process its output using the sort -k2,2 command. Run the freqL script: ./freqL.sh text.txt The output of freqL.sh will resemble the following: 2 b 1 s 1 n...

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...
