编辑 /etc/profile 后出现“未找到命令”

我关注了教程为所有用户添加 JAVA 变量。然后我打开托管服务提供的编辑器并添加最后两行。Centos 5.9服务器。

# /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

重新登录后我得到：

问题是我需要配置 Java home 变量。即使我删除最后两行添加的内容，仍然会收到该错误。 谢谢。

看起来您使用的编辑器将换行符 ('\n')（数值上等于换行符 (LF)）更改为 CR+LF 序列（CR = 回车符）。总的来说，您显示的错误消息没有多大意义，但这一部分引起了我的注意：

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

这就是说“意外的标记”后面跟着{一个 CR。
