編輯 /etc/profile 後“找不到命令”

我跟著這個教學為所有使用者新增 JAVA 變數。然後，我打開託管服務提供的編輯器並添加最後兩行。森托斯 5.9伺服器.

# /etc/profile
    
# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc

pathmunge () {
    if ! echo $PATH | /bin/egrep -q "(^|:)$1($|:)" ; then
       if [ "$2" = "after" ] ; then
          PATH=$PATH:$1
       else
          PATH=$1:$PATH
       fi
    fi
}

# ksh workaround
if [ -z "$EUID" -a -x /usr/bin/id ]; then 
    EUID=`id -u`
    UID=`id -ru`
fi

# Path manipulation
if [ "$EUID" = "0" ]; then
    pathmunge /sbin
    pathmunge /usr/sbin
    pathmunge /usr/local/sbin
fi

# No core files by default
ulimit -S -c 0 > /dev/null 2>&1

if [ -x /usr/bin/id ]; then
    USER="`id -un`"
    LOGNAME=$USER
    MAIL="/var/spool/mail/$USER"
fi

HOSTNAME=`/bin/hostname`
HISTSIZE=1000

if [ -z "$INPUTRC" -a ! -f "$HOME/.inputrc" ]; then
    INPUTRC=/etc/inputrc
fi

export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC

# By default, we want umask to get set. This sets it for login shell
# Current threshold for system reserved uid/gids is 200
# You could check uidgid reservation validity in
# /usr/share/doc/setup-*/uidgid file
if [ $UID -gt 99 ] && [ "`id -gn`" = "`id -un`" ]; then
    umask 002
else
    umask 022
fi

for i in /etc/profile.d/*.sh ; do
    if [ -r "$i" ]; then
        if [ "${-#*i}" != "$-" ]; then
            . $i
        else
            . $i >/dev/null 2>&1
        fi
    fi
done

unset i
unset pathmunge
#cPanel Added local::lib -- BEGIN
LOCALLIBUSER=$USER
if [ -e "/usr/bin/whoami" ]; then
        LOCALLIBUSER=`/usr/bin/whoami`
fi
if [ "$LOCALLIBUSER" != "root" ]; then
    eval $(perl -Mlocal::lib)
fi
#cPanel Added local::lib -- END

export PATH=$PATH:/opt/java/jdk1.6.0_41/bin
export PATH=$PATH:/opt/java/jdk1.6.0_41/bin

重新登入後我得到：

問題是我需要配置 Java home 變數。即使我刪除了最後兩行添加的內容，我仍然收到該錯誤。謝謝。

它看起來非常像您使用的編輯器將換行符（'\n'）字元（在數字上等於換行（LF）字元）更改為 CR+LF 序列（CR = 回車符）。總的來說，您顯示的錯誤訊息沒有多大意義，但這部分讓我感到驚訝：

…bash: /etc/profile: line 6: syntax error near unexpected token `{
'

也就是說，「意外標記」後面跟著{一個 CR。
