安装Linux的时候选择了中文版,桌面的目录就在 $HOME目录下的”桌面”目录;
在gnome terminal要进这个目录,从RedHat、FC,到RHEL,Ubuntu,没少烦过我:每次敲cd命令后还要把输入法切换到中文,再输入” 桌面”;
后来找到一下办法:在.bashrc中export d=~/桌面/,要进“桌面”目录也就输入: “cd $d”
这时,问题又来了:
要把桌面的某个文件移到别的地方,敲mv $d/之后按TAB,bash竟然帮我补全成: “mv \$d/”….无语….

- complete -o default -F _longopt mv

解决的办法:在_filedir()函数中把 “$d”替换掉,因此在_filedir()函数最后增加代码:
- local cnt=0
- while [ $cnt -lt ${#COMPREPLY[@]} ];
- do
- local v=${COMPREPLY[$cnt]}
- if [[ ${v:0:1} == “{1}quot; ]]; then
- COMPREPLY[$cnt]=$(eval echo “$v”)
- fi
- ((cnt++))
- done
- _filedir()
- {
- local i IFS=$\‘\n\’ xspec
- _tilde “$cur” || return 0
- local -a toks
- local quoted tmp
- _quote_readline_by_ref “$cur” quoted
- toks=( ${toks[@]-} $(
- compgen -d — “$quoted” | {
- while read -r tmp; do
- # TODO: I have removed a “[ -n $tmp ] &&” before ‘printf ..’,
- # and everything works again. If this bug suddenly
- # appears again (i.e. “cd /b<TAB>” becomes “cd /”),
- # remember to check for other similar conditionals (here
- # and _filedir_xspec()). –David
- printf ‘%s\n’ $tmp
- done
- }
- ))
- if [[ “$1” != -d ]]; then
- # Munge xspec to contain uppercase version too
- [[ ${BASH_VERSINFO[0]} -ge 4 ]] && \
- xspec=${1:+“!*.@($1|${1^^})”} || \
- xspec=${1:+“!*.@($1|$(printf %s $1 | tr ‘[:lower:]’ ‘[:upper:]’))”}
- toks=( ${toks[@]-} $( compgen -f -X “$xspec” — $quoted) )
- fi
- [ ${#toks[@]} -ne 0 ] && _compopt_o_filenames
- # If the filter failed to produce anything, try w/o it (LP: #533985)
- if [[ -n “$1” ]] && [[ “$1” != -d ]] && [[ ${#toks[@]} -lt 1 ]] ; then
- toks=( ${toks[@]-} $( compgen -f -X — $quoted) )
- fi
- COMPREPLY=( “${COMPREPLY[@]}” “${toks[@]}” )
- local cnt=0
- while [ $cnt -lt ${#COMPREPLY[@]} ];
- do
- local v=${COMPREPLY[$cnt]}
- if [[ ${v:0:1} == “{1}quot; ]]; then
- COMPREPLY[$cnt]=$(eval echo “$v”)
- fi
- ((cnt++))
- done
- }
