我试图在此代码中添加一个条件,例如,如果翻译文件中的 string 或 repl[string] 存在空字符串,则我的文件 input_chk.txt 具有以下详细信息:
输入_chk.txt
b73_chr10 w22_chr2
w22_chr7 w22_chr10
w22_chr8
代码 :
#!/usr/bin/awk -f
# Collect the translations from the first file.
NR==FNR { repl[$1]=$2; next }
# Step through the input file, replacing as required.
{
if
for ( string in repl ) {
if (length(string)==0)
{
echo "error"
}
else
{
sub(string, repl[string])
}
}
#if string is null-character,then we have to add rules,
#if repl[string] is null-character,then we have to delete rules or put # in front of all lines until we reach </rules> also
# And print.
1
# to run this script as $ ./bash_script.sh input_chk.txt file.conf
文件.conf
<rules>
<rule>
condition =between(b73_chr10,w22_chr1)
color = ylgn-9-seq-7
flow=continue
z=9
</rule>
<rule>
condition =between(w22_chr7,w22_chr2)
color = blue
flow=continue
z=10
</rule>
<rule>
condition =between(w22_chr8,w22_chr3)
color = vvdblue
flow=continue
z=11
</rule>
</rules>
但是,我的代码在第 8 行显示错误。如何包含条件,以便在第一列或第二列中缺少字符串时可以打印错误。
答案1
运行脚本发现问题:
- 第 8 行是一个语法错误,这个词
if
本身就是一个。 - 第 21 行是一个语法错误,这个词
1
本身就是一个语法错误。
将这些注释掉,第 6 行有一个悬空。{
也许这是从某个工作脚本复制的,其中第 3 行有趣的记录收集语句在结论中进行处理。
{
通过添加前缀来修复脚本END
。将第 21 行更改1
为}
.
现在(至少)脚本在语法上是正确的,并且没有错误。结果如下:
#!/usr/bin/awk -f
# Collect the translations from the first file.
NR==FNR { repl[$1]=$2; next }
# Step through the input file, replacing as required.
END {
#if
for ( string in repl ) {
if (length(string)==0)
{
echo "error"
}
else
{
sub(string, repl[string])
}
}
#if string is null-character,then we have to add rules,
#if repl[string] is null-character,then we have to delete rules or put # in front of all lines until we reach </rules> also
# And print.
}
# to run this script as $ ./bash_script.sh input_chk.txt file.conf
然而,它没有任何用处。做到这一点那至少还有一个问题。
