tr: Replace all occurrences of a character from another command's output.
$ echo ${text} | tr ${find_character} ${replace_character}
try on your machine
This command is used to replace a specific character in a string or text with another character. Let's break down the command:
echo ${text}
: This part outputs the value of the variable${text}
. The variable${text}
should be assigned a string or a text that you want to modify.|
: This is called the pipe operator and it is used to redirect the output of the preceding command to the input of the succeeding command.tr ${find_character} ${replace_character}
: This part uses thetr
command to perform the character replacement. The variable${find_character}
should contain the character you want to find, and the variable${replace_character}
should contain the character you want to replace it with.
To give an example, let's say we have the following command:
echo "Hello, world!" | tr o e
This command will replace all occurrences of the letter 'o' with the letter 'e' in the string "Hello, world!". So, the output of this command would be:
Hello, werld!
Note that the tr
command only replaces single characters, not multiple characters or substrings.
