'newline unexpected' Error in BASH script
提问by Danijel Janosevic
I have SHARED.SH file:
我有 SHARED.SH 文件：
#!/bin/sh
g_dlg_yes=1
g_dlg_no=0
g_dlg_cancel=2
g_dlg_unknown=127
show_confirm_dlg()
{
prompt=$*
resp=""
while [ "$resp" != "y" ] && [ "$resp" != "n" ] && [ "$resp" != "c" ]; do
echo "${prompt} [y/n/c]: "
read resp
done
case "$resp" in
y ) return g_dlg_yes;;
n ) return g_dlg_no;;
c ) return g_dlg_cancel;;
* ) return g_dlg_unknown;;
Esac
}
Also I have INSTALL.SH file:
我还有 INSTALL.SH 文件：
#!/bin/sh
. ./shared.sh
install_pkg()
{
clear
pkg_name=$*
prompt="Do you want to install ${pkg_name}?"
show_confirm_dlg $pkg_name
res=$?
if [ "$res" -eq g_dlg_cancel ]; then
echo "Installation of $pkg_name cancelled."
exit 2
elif [ "$res" -eq g_dlg_no ]; then
echo "Installation of $pkg_name rejected."
elif [ "$res" -eq g_dlg_yes ]; then
echo "Trying to install $pkg_name..."
apt-get install -y $pkg_name
else
echo "Unknown answer. Now quitting..."
exit 2
fi
echo "Press ENTER to continue..."
read key
}
main()
{
install_pkg "dosbox virtualbox"
exit $?
}
main
When I try to run INSTALL.SH the following error occurs: ./install.sh: 22: ./shared.sh: Syntax error: newline unexpected (expecting ")")
当我尝试运行 INSTALL.SH 时出现以下错误 ：./install.sh: 22: ./shared.sh: Syntax error: newline unexpected (expecting ")")
Could you help me with this error, please?
你能帮我解决这个错误吗？

Bash commands and statements are case-sensitive.
The esaccommand in your SHARED.SH file is in the wrong case.
Bash 命令和语句区分大小写。esacSHARED.SH 文件中的命令大小写错误。
#!/bin/sh
g_dlg_yes=1
g_dlg_no=0
g_dlg_cancel=2
g_dlg_unknown=127
show_confirm_dlg()
{
prompt=$*
resp=""
while [ "$resp" != "y" ] && [ "$resp" != "n" ] && [ "$resp" != "c" ]; do
echo "${prompt} [y/n/c]: "
read resp
done
case "$resp" in
y ) return g_dlg_yes;;
n ) return g_dlg_no;;
c ) return g_dlg_cancel;;
* ) return g_dlg_unknown;;
esac
}
