[LINUX] Search for character strings in files [Comparison between Bash and PowerShell]

Return to Bash and PowerShell command correspondence table

I just learned how to do PowerShell.

Bash

Command format

$ grep [option] <The character string you want to search> [file name]

# [option]: 任意（以下は、私がよく使うoption）
    -i:Search in case insensitive
    -I:Exclude binary files from search
    -n:Display the line number of the part that was caught in the search
    -r:Also search for files in subdirectories
    -v: <The character string you want to search>Show what does not match
    -w:Show only exact matches
    --exclude="*.extension": 指定したextensionは検索対象外にする
    --include="*.extension": 指定したextensionのみ検索対象にする

# <The character string you want to search>:Mandatory
If space is included in the middle, ""String string"Enclose in double quotes.

# [file name]:Optional (but close to mandatory)
Search only in the specified file.
fundamentally"*(Asterisk): All files can be searched.
I want to narrow down the search target (for example, hoge).Specify a specific file name only when (txt file only).

Example of use

Example 1) Search for all files in the current directory with hoge

$ grep hoge *

Example 2) Search for the hoge.txt file in the current directory with hoge

$ grep hoge hoge.txt

Example 3) Search for exact matches with main for all files including subdirectories

$ grep -rw main *

Example 4) Search for all files including subdirectories that do not contain main

$ grep -rv main *

Example 5) Search by color for all files other than json and xml files including subdirectories

$ grep -r --exclude="*.json" --exclude="*.xml" color *
