ubuntu14.04 配置java变量不小心清除了etc/profile,怎么办？

[Junior_s]

刚接触linux，新安装的ubuntu14.04单系统，配置java环境变量时用vim编辑etc/profile文件，由于操作不熟练，致使文件打开时只能看到一行代码：export JAVA_HOME=/usr/local/java/jdk1.8.0_111
，我重启了几次系统都能正常进入，但打开这个文件还只是这一行，请问这个文件影响大吗？对开发环境影响大吗？如果影响大的话？能恢复原文件吗？有热心网友说拷贝其他14.04电脑的profile文件就可以，哪位好心人有？

最好还是重新拷贝 不行的话自己重新找台电脑安装一下，然后拷贝出来。

给你参考一下： # /etc/profile: system-wide .profile file for the Bourne shell (sh(1)) # and Bourne compatible shells (bash(1), ksh(1), ash(1), ...). if [ "$PS1" ]; then if [ "$BASH" ] && [ "$BASH" != "/bin/sh" ]; then # The file bash.bashrc already sets the default PS1. # PS1='\h:\w\$ ' if [ -f /etc/bash.bashrc ]; then . /etc/bash.bashrc fi else if [ "`id -u`" -eq 0 ]; then PS1='# ' else PS1='$ ' fi fi fi # The default umask is now handled by pam_umask. # See pam_umask(8) and /etc/login.defs. if [ -d /etc/profile.d ]; then for i in /etc/profile.d/*.sh; do if [ -r $i ]; then . $i fi done unset i fi
