安裝Linux的時候選擇了中文版,桌面的目錄就在 $HOME目錄下的"桌面"目錄;
在gnome terminal要進這個目錄,從RedHat、FC,到RHEL,Ubuntu,沒少煩過我:每次敲cd命令後還要把輸入法切換到中文,再輸入" 桌面";
後來找到一下辦法:在.bashrc中export d=~/桌面/,要進“桌面"目錄也就輸入: "cd $d"
這時,問題又來了:
要把桌面的某個文件移到別的地方,敲mv $d/之後按TAB,bash竟然幫我補全成: "mv \$d/"....無語....

- complete -o default -F _longopt mv

剛開始以為是,default行為或_longopt函數搞的鬼,跟蹤了一下發現_longopt調用了_filedir()函數,_filedir()處理完了還沒有把"$"號變成“\$",結論:bash後面又處理了一下
解決的辦法:在_filedir()函數中把 "$d"替換掉,因此在_filedir()函數最後增加代碼:
- 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
最後_filedir()函數變成:
- _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
- }
