CORRECTION PARAMETERS FOR THE STANDARD ERROR OF REFLECTION INTENSITIES
******************************************************************************
The variance v0(I) of the intensity I obtained from counting statistics is
replaced by v(I)=a*(v0(I)+b*I^2). The model parameters a, b are chosen to
minimize the discrepancies between v(I) and the variance estimated from
sample statistics of symmetry related reflections. This model implicates
an asymptotic limit ISa=1/SQRT(a*b) for the highest I/Sigma(I) that the
experimental setup can produce (Diederichs (2010) Acta Cryst D66, 733-740).
Often the value of ISa is reduced from the initial value ISa0 due to systematic
errors showing up by comparison with other data sets in the scaling procedure.
(ISa=ISa0=-1 if v0 is unknown for a data set.)

Corr of anomalous intensity differences. Correlation
significant at the 0.1% level is marked.
SigAno = mean anomalous difference in units of its estimated
standard deviation (|F(+)-F(-)|/Sigma). F(+), F(-)

cpu time used by XSCALE 25.9 sec
elapsed wall-clock time 28.1 sec我想提取倒数第二行，其中第11列包含一个数字，后跟一个星号(xy.z*)。例如，在此表中，我要查找的行将包含第11列中的"23.2*“(CC(1/2))。我想要倒数第二行，因为最后一行是以total开头的行，使用简单的grep命令可以更容易地提取它。
因此，本例中代码的预期输出将是打印行：
1.50 273432 20770 20893 99.4% 333.4% 342.1% 273340 0.80 346.9% 23.2* -1 0.644 19495在另一个文件中，第11列中倒数第二个带有星号的值可能对应于第一列中的1.6，因此预期输出为：
1.60 216910 5769 5769 100.0% 207.5% 214.7% 216910 1.72 210.4% 26.0* -3 0.654 5204以此类推，以此类推，表中星号的所有可能位置。
我尝试过使用grep "0-9，0-9，.，0-9*“file.name和其他grep和fgrep之类的东西，但我对此还很陌生，无法让它正常工作。
任何帮助都将不胜感激。

下面这一行代码可以做到：
$ awk '{if ($11 ~ /\*/) {i++; a[i]=$0}} END {print a[i -1]}' file
1.50 274090 20781 20874 99.6% 333.7% 341.9% 274015 0.80 347.1% 24.8* 0 0.645 19516解释
它将包含第11个字段的所有行添加到数组a[]中。然后打印的不是最后一个，而是前一个。
更新
由于您的日志非常大，并且到处都是星号，因此我将代码更新为：
$ awk '{if ($11 == /[0-9]*.[0-9]*\*/) {i++; a[i]=$0}} END {print a[i -1]}' a
0.90 0 0 147505 0.0% -99.9% -99.9% 0 -99.00 -99.9% 0.0 0 0.000 0因此，它查找NNN.XXX*格式的行。

awk '$11~/^[0-9.]+\*$/ {prev=val; val=$11+0} END {print prev}' log我在$11的值上加上0，将字符串" 23.2 *“转换为数字23.2。
或者，当我听到"nth from the end“时，我会想:颠倒过来，从顶部取第n个：
tac log | awk '$11~/^[0-9.]+\*$/ && ++n == 2 {print $11+0; exit}'页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
