当我尝试在 Ubuntu 终端中更新(源 .bashrc)我的 .bashrc 以更改别名时,我收到错误
bash: ./.bashrc: line 34: syntax error near unexpected token `then'
bash: ./.bashrc: line 34: `if [ -z "${debian_chroot:-}" ] && [ -r /etc/debian_chroot ]; then'
这是.bashrc中的这段代码:
# set variable identifying the chroot you work in (used in the prompt below)
if [ -z "${debian_chroot:-}" ] && [ -r /etc/debian_chroot ]; then
debian_chroot=$(cat /etc/debian_chroot)
fi
在 .bashrc 的顶部添加 set -x,我得到以下关于输出的额外信息:
+ source .bashrc
++ case $- in
++ HISTCONTROL=ignoreboth
++ shopt -s histappend
++ HISTSIZE=1000
++ HISTFILESIZE=2000
++ shopt -s checkwinsize
++ '[' -x /usr/bin/lesspipe ']'
+++ SHELL=/bin/sh
+++ lesspipe
++ eval 'export LESSOPEN="| /usr/bin/lesspipe %s";
export LESSCLOSE="/usr/bin/lesspipe %s %s";'
+++ export 'LESSOPEN=| /usr/bin/lesspipe %s'
+++ LESSOPEN='| /usr/bin/lesspipe %s'
+++ export 'LESSCLOSE=/usr/bin/lesspipe %s %s'
+++ LESSCLOSE='/usr/bin/lesspipe %s %s'
我已通过 /etc/skel 将 .bashrc 恢复为默认值,但错误仍然出现,因为这部分代码似乎是默认的。下面是我完整的 .bashrc 文件。

有谁知道这个问题的解决方案?

steeldriver 说得对
问题是你的别名如果。您可以注释掉第 141 行,并将其添加到 .bashrc 的开头
alias if='if'
对于下一个源.bashrc。
此后,您可以删除别名 if 并将第 141 行更改为类似
alias if-foo='cd ~/Tetra/Run_Mediterranean/Run_faults/I_0'
