是否有一种简单的方法可以打印file.txt的完整路径?
file.txt = /nfs/an/disks/jj/home/dir/file.txt
<命令>
dir> <command> file.txt
应该打印
/nfs/an/disks/jj/home/dir/file.txt

这对我来说很有效。它不依赖于文件系统(取决于需要的利弊),所以它会很快;并且,它应该可以移植到大多数*NIX。它假设传递的字符串确实是相对于PWD,而不是其他目录。
function abspath () {
echo $1 | awk '\
# Root parent directory refs to the PWD for replacement below
/^\.\.\// { sub("^", "./") } \
# Replace the symbolic PWD refs with the absolute PWD \
/^\.\// { sub("^\.", ENVIRON["PWD"])} \
# Print absolute paths \
/^\// {print} \'
}

除了"readlink -f",还有一个常用的命令:
$find /the/long/path/but/I/can/use/TAB/to/auto/it/to/ -name myfile /the/long/path/but/I/can/use/TAB/to/auto/it/to/myfile $
这也给出了控制台的完整路径和文件名
跑题:这种方法只给出相对链接,而不是绝对链接。readlink -f命令是正确的。
创建一个如下所示的函数(使用pwd回显文件的绝对路径,并将文件添加到路径的末尾:
abspath() { echo $(pwd "$1")/"$1"; }
现在你可以找到任何文件路径:
abspath myfile.ext
you@you:~/test$ ls
file
you@you:~/test$ path="`pwd`/`ls`"
you@you:~/test$ echo $path
/home/you/test/file
这很天真,但是我必须使它与POSIX兼容。需要进入文件目录的cd权限。
#!/bin/sh
if [ ${#} = 0 ]; then
echo "Error: 0 args. need 1" >&2
exit 1
fi
if [ -d ${1} ]; then
# Directory
base=$( cd ${1}; echo ${PWD##*/} )
dir=$( cd ${1}; echo ${PWD%${base}} )
if [ ${dir} = / ]; then
parentPath=${dir}
else
parentPath=${dir%/}
fi
if [ -z ${base} ] || [ -z ${parentPath} ]; then
if [ -n ${1} ]; then
fullPath=$( cd ${1}; echo ${PWD} )
else
echo "Error: unsupported scenario 1" >&2
exit 1
fi
fi
elif [ ${1%/*} = ${1} ]; then
if [ -f ./${1} ]; then
# File in current directory
base=$( echo ${1##*/} )
parentPath=$( echo ${PWD} )
else
echo "Error: unsupported scenario 2" >&2
exit 1
fi
elif [ -f ${1} ] && [ -d ${1%/*} ]; then
# File in directory
base=$( echo ${1##*/} )
parentPath=$( cd ${1%/*}; echo ${PWD} )
else
echo "Error: not file or directory" >&2
exit 1
fi
if [ ${parentPath} = / ]; then
fullPath=${fullPath:-${parentPath}${base}}
fi
fullPath=${fullPath:-${parentPath}/${base}}
if [ ! -e ${fullPath} ]; then
echo "Error: does not exist" >&2
exit 1
fi
echo ${fullPath}
你可以使用fpn(完整路径名)脚本:
% pwd
/Users/adamatan/bins/scripts/fpn
% ls
LICENSE README.md fpn.py
% fpn *
/Users/adamatan/bins/scripts/fpn/LICENSE
/Users/adamatan/bins/scripts/fpn/README.md
/Users/adamatan/bins/scripts/fpn/fpn.py
fpn不是一个标准的Linux包,但它是一个免费开放的github项目,你可以在一分钟内设置好。
