那么grep呢:

pwd | grep -o '[^/]*$'

以下命令将在bash脚本中打印当前工作目录。

pushd .
CURRENT_DIR="`cd $1; pwd`"
popd
echo $CURRENT_DIR

$ echo "${PWD##*/}"

​​​​​

不需要basename，特别是不需要运行pwd的子shell(这会增加额外且昂贵的fork操作);shell可以在内部使用参数展开:

result=${PWD##*/}          # to assign to a variable
result=${result:-/}        # to correct for the case where PWD=/

printf '%s\n' "${PWD##*/}" # to print to stdout
                           # ...more robust than echo for unusual names
                           #    (consider a directory named -e or -n)

printf '%q\n' "${PWD##*/}" # to print to stdout, quoted for use as shell input
                           # ...useful to make hidden characters readable.

请注意，如果在其他情况下应用此技术(不是PWD，而是包含目录名的其他变量)，则可能需要修剪任何尾随的斜杠。下面使用bash的extglob支持，即使使用多个尾随斜杠也能正常工作:

dirname=/path/to/somewhere//
shopt -s extglob           # enable +(...) glob syntax
result=${dirname%%+(/)}    # trim however many trailing slashes exist
result=${result##*/}       # remove everything before the last / that still remains
result=${result:-/}        # correct for dirname=/ case
printf '%s\n' "$result"

或者，不使用extglob:

dirname="/path/to/somewhere//"
result="${dirname%"${dirname##*[!/]}"}" # extglob-free multi-trailing-/ trim
result="${result##*/}"                  # remove everything before the last /
result=${result:-/}                     # correct for dirname=/ case

basename $(pwd)

or

echo "$(basename $(pwd))"

对于像我这样的骑手来说

find $PWD -maxdepth 0 -printf "%f\n"
