Append a character to the out using unix command-CodePudding

echo 20220506 | cut -c5-6 gives the output as

I want add a '/' at the end of the output(05/). Can someone kindly help?

CodePudding user response：

Try

echo 20220506 | cut -c5-6 | sed 's/$/\//'

Sed is stream editor and s/$/\// means

s : substitute
$ : end of line
\/ : / escaped with \
other slashes (/) : separator character of parameters to substitution operator.

Instead of using a pipe | character, you could use backticks to evaluate your command inside another command.

echo `echo 20220506 | cut -c5-6`/
