Step 1: Enter vim editor
vim /etc/ssh/ssh_config
Step 2: Search method
Method 1: Quick search (exact string match, case sensitive)
Format: / + keyword or ? + keywords
/Port #按回车键搜索 从上到下查找
？Port #按回车键搜索 从下到上查找
Advantages: quickly locate the keyword
After pressing Enter, press n to search for the next matching result that appears, and press uppercase N to search for the next matching result that appears in reverse.
Method 2: Whole word search
Format: / + \< + keyword + \>
/\<Iden\>
After pressing Enter, press * to search forward or # backward.
Step 3: Search History
Format: / + up and down arrow keys
press enter after selection
Step 4: Case Sensitive
By default, searches are case sensitive. Searching for "YES" will not match "yes".
:set ignorecaseTo ignore case, enter or on the Vim command line :set ic. You can also add a default option to your ~/.vimrcfile to ignore case.
To change back to case-sensitive, enter :set noignorecaseor :set noic.
Another way to force case to be ignored is to add it after the search pattern \c. For example, /Linux\ccase sensitivity will be ignored when searching. Adding uppercase after the search style \Cwill force case sensitivity.
