Cshell 脚本中，while: Expression Syntax.

[qq_18751439]

求助 为什么代码总是出现这个语法错误

#-------------------------------------------------------------------------------------------------

while [ $id -le $ens_size ]
do

if [ $id -lt $n1 ]
then
string1=$name1$s2$id
string2=$name2$s2$id
fi

if [ $id -ge $n1 ] ; then
string1=$name1$id$name3
string2=$name2$id$name3
fi

echo $id $ens_size $string
echo $string1
echo $string2

#----------------------------------------------------------

rpath1=$home/$string1
rpath2=$home/$string2

cd $home

rm -r $rpath1
rm -r $rpath2

mkdir $rpath1
mkdir $rpath2

id=`echo "$id + 1" | bc`

done

是否哪个语法字段有格式的问题

csh的语法和bash不一样。 这个看起来像bash的语法。

http://www.tcsh.org/tcsh.html/Builtin_commands.html#while while (expr) ... end Executes the commands between the while and the matching end while expr (an expression, as described under Expressions) evaluates non-zero. while and end must appear alone on their input lines. break and continue may be used to terminate or continue the loop prematurely. If the input is a terminal, the user is prompted the first time through the loop as with foreach.
