此脚本似乎给出不一致的结果。例如,当if
语句看到其第一个较大的字符串时,它可以正常工作。但是,有时较大的后来的字符串会被完全忽略:
ITEM[0]="XX"
ITEM[1]="XXXXXXX"
ITEM[2]="X"
ITEM[3]="XXXXXXXXXXXX"
ITEM[4]="XXXX"
SETPOINT=0
for i in "${!ITEM[@]}"; do
STRING="${ITEM[$i]}"
LENGTH=${#STRING}
echo "String length = $LENGTH"
if [ $LENGTH \> $SETPOINT ]; then
SETPOINT=$LENGTH
echo "Setpoint was updated to $SETPOINT"
fi
echo "Loop again"
done
echo "Final setpoint = $SETPOINT"
这是示例输出:
String length = 2
Setpoint was updated to 2
Loop again
String length = 7
Setpoint was updated to 7
Loop again
String length = 1
Loop again
String length = 12 <--- Why didn't it catch this one?????
Loop again
String length = 4
Loop again
Final setpoint = 7
此外,最初我尝试在if
语句中进行变量扩展和字符串计数,因此我不必创建“ STRING”和“ LENGTH”,但是我无法弄清楚语法在if
内同时扩展数组变量并同时计算字符串。因此,如果您也为了缩短代码而对此有所考虑,那就太好了!
谢谢!

将glTexImage3D(GL_TEXTURE_2D_ARRAY, 0, GL_RGBA, dev->atlas_width, dev->atlas_height,
dev->atlas_depth, 0, GL_RGBA, GL_UNSIGNED_BYTE, NULL);
glTexSubImage3D(GL_TEXTURE_2D_ARRAY, 0, dev->atlas_offset_x, dev->atlas_offset_y,
dev->atlas_offset_z, width, height, 1, GL_RGBA, GL_UNSIGNED_BYTE, image);
替换为\>
