Changing to parent directory in unix

Question

In general, I used the

cd .. for moving to your parent directory

cd ../../ to go to a parents parent directory. and

cd ../../../../../ for fifth parent directory.

is there any other way of doing this?

The shell I am using is ksh.

Answer 1

This is the function used for Bash, but something similar could be done for others, for example:

cdn () { pushd .; for ((i=1; i<=$1; i++)); do cd ..; done; pwd; }

Example usage:

/some/dirs/and/subdirs$ cdn 3

/some/dirs/and/subdirs /some/dirs/and/subdirs

/some

/some$ popd

/some/dirs/and/subdirs$

Here is a function that will cd to a named subdirectory above the current working directory:

cdu () { cd "${PWD%/$1/*}/$1"; }

Example usage:

/usr/share/atom/resources/app/apm/src/generator$ cdu apm

/usr/share/atom/resources/app/apm$ cdu resources

/usr/share/atom/resources$ cd -

/usr/share/atom/resources/app/apm$ cdu share

/usr/share
